Can Drinking Too Much Water Cause Low Potassium
Its not common, but it can happen. It would be best if you drank enough to replace what you lose through sweating. Overexercising can lead to excessive fluid loss. This means that youll need to consume additional fluids to replenish those lost.
It would help if you didnt worry, though most cases of low potassium dont result in any serious health issues. The symptoms usually disappear after several days.
Most adults only sweat around 1-2 liters per hour while sleeping. So unless you work out every single second of the night, you wont run out of liquid before morning!
Should I Be Concerned About Having High Blood Pressure And A Low Pulse
If youre taking blood pressure medication and have slightly high blood pressure and a low pulse, this generally isnt anything to be concerned about.
But if youre not taking any medication, its best to work with a doctor to figure out whats going on. This is especially true if you have symptoms of a low pulse, such as dizziness or shortness of breath.
The typical range of 60 to 100 beats per minute is both the average pulse measurement as well as the rate at which most peoples heart needs to beat to pump enough blood through their body.
Some people may simply have a lower pulse. Examples include athletes or those in very good shape. Theyve conditioned their heart muscle to be stronger. As a result, their heart pumps more effectively, meaning it doesnt need to beat as often. Learn more about why athletes have lower pulses.
Exercising can also temporarily raise your blood pressure. So, if you exercise regularly, you may have a naturally low pulse and higher blood pressure right after you work out.
Understanding Your Heart Rate By The Numbers
You can measure your own heart rate. First, find your heart rate by holding a finger to the radial artery at the wrist. Then, count the number of beats per minute while youre resting.
Other places your heart rate can be measured are at the neck , the groin , and the feet .
Here are some numbers to keep in mind:

The Inner Ear And Balance
Inside the inner ear is a series of canals filled with fluid. These canals are oriented at different angles and, as the head moves, the movement of the fluid inside these canals tells the brain how far, how fast and in what direction the head is moving.This information is then used by the brain to move the eyes an equal and opposite amount, so that the image that is seen by the eyes does not blur and remains clear.
Understanding A Slow Heart Rate
It’s common to experience a slow heart rate as you get older, but it’s also something that your doctor needs to monitor. Find out what a slow heart rate means for your health, and when it’s time to seek treatment.
Its common for everyones heart beat rate to slow down at rest, but some people have a chronically slow heart rate that causes symptoms such as fatigue and lightheadedness.
This condition is called bradycardia, and its more common as you age. Mild cases of bradycardia dont have symptoms, but in severe cases it can cause chest pain, shortness of breath, and may even lead to cardiac arrest.
Are you doing everything you can to manage your heart condition? Find out with our interactive checkup.
A normal heart beat rate is between 60 and 100 beats a minute, says Joshua D. Moss, MD, a cardiologist at the Heart Rhythm Center at the University of Chicago Medical Center. Bradycardia is defined as having a heart rate of less than 60 beats a minute. In reality, you can have periods when your heart beat rate goes below 60 and not have bradycardia, Dr. Moss says. It can happen when youre sleeping, or it can occur in highly conditioned athletes when theyre at rest.
How Bradycardia Is Detected
You may be prompted to find out if you have a slow heart rate if you have certain symptoms. However, some people with the condition dont have any symptoms.

You Might Have Low Blood Pressure
Myocarditis, or inflammation of the heart muscle, is a potentially dangerous effect of COVID-19. “Myocarditis can result from direct heart invasion by the virus itself, or more commonly by inflammation caused by cytokine storm,” wrote Dara K. Lee Lewis of Harvard Medical School earlier this month. “When this occurs, the heart may become enlarged and weakened, leading to low blood pressure and fluid in the lungs.”
Treatment Of Low Heart Rate
In patients with confirmed or suspected slow heart rate, the underlying possible causes such as those outlined above need to be evaluated carefully. Its especially important to review the medication list carefully and stop any potentially offending agents. Blood tests such as thyroid function studies may be performed.
An EKG is performed to see if there is just a slow heart rate or any evidence of heart block. Sometimes a monitor is worn to see the heart rate over time. Some people with a slow heart rate are unable to get their heart rate up with exercise known as chronotropic incompetence this can be diagnosed with exercise testing. An echocardiogram may be performed to evaluate the heart structure and function.
What we do with a slow heart rate really depends on how bad the symptoms are. Its key to make sure the symptoms are related to the slow heart rate and that possible causes are identified and treated. The main indication for a patient without symptoms to get a pacemaker would be advanced heart block, long pauses in the heartbeat or rhythms that have the potential to lead to instability.
In patients that are symptomatic, and in whom underlying reversible causes have been ruled out, insertion of a pacemaker may be required. The choice of pacemaker for those with a low heart rate is different in different people and depends upon the level of block in the heart.

What You Can Do Now
It can be difficult to interpret the symptoms on your own. Swollen lower extremities, fatigue, irregular heart rhythm, and other symptoms can indicate any number of heart issues or other illnesses.
Its wise to develop a relationship with a doctor whos familiar with your family and personal history. A doctor who knows your habits and lifestyle will be better able to diagnose your illness.
See your doctor before you experience the symptoms of heart disease. Get regular checkups, and listen to your doctors advice for living a healthier lifestyle.
In addition to seeing a doctor regularly, you should also make positive changes to your lifestyle. This includes the following:
- Stop smoking tobacco.
How Are Blood Pressure Problems Treated In Patients With Dizziness
Patients who experience lightheadedness and dizziness often have poor circulationand the sensations can be most apparent when sitting up or standing, particularly after having been seated or reclining for several hours.
Dizziness is also a common symptom of the blood pressure medications such as alpha channel blockers or calcium channel blockers, and prostate medication. If patients are taking those medications, the best treatment for their dizziness is to consult with their primary care physicians to determine if switching medication is possible.
Another treatment approach is to educate patients about symptom management. Before standing up suddenly, for example, you can improve circulation by repeatedly contracting your thigh muscles. Or instead of immediately getting out of bed in the morning, try raising your head by about three inches, which increases the tone of blood vessels so pressure doesnt drop after standing up. Compression stockings also work to increase arterial pressure and reduce the chance of a sudden blood pressure drop.

When Heart Rate Or Rhythm Changes Are Minor
Many changes in heart rate or rhythm are minor and do not require medical treatment if you do not have other symptoms or a history of heart disease. Smoking, drinking alcohol or caffeine, or taking other stimulants such as diet pills or cough and cold medicines may cause your heart to beat faster or skip a beat. Your heart rate or rhythm can change when you are under stress or having pain. Your heart may beat faster when you have an illness or a fever. Hard physical exercise usually increases your heart rate, which can sometimes cause changes in your heart rhythm.
Dietary supplements, such as goldenseal, oleander, motherwort, or ephedra , may cause irregular heartbeats.
It is not uncommon for pregnant women to have minor heart rate or rhythm changes. These changes usually are not a cause for concern for women who do not have a history of heart disease.
Well-trained athletes usually have slow heart rates with occasional pauses in the normal rhythm. Evaluation is usually not needed unless other symptoms are present, such as lightheadedness or fainting , or there is a family history of heart problems.
How Prednisone Affects Heart Rate
Prednisone is a corticosteroid used to treat a number of inflammatory conditions, including severe allergic reaction, certain forms of arthritis, endocrine disorders, and immune system disorders. It is also used to treat certain types of cancer.
However, prednisone comes with many side effects, one of which is a change in heart rate. This medication can cause irregular potassium, calcium, and phosphate levels, which can cause heartbeat irregularities.
Prednisone is used to treat a wide variety of conditions.

Other Heart Electrical Issues
The heart communicates by sending electrical signals. For example, one chamber of the heart sends electrical signals to another, telling it how and when to squeeze blood into the next chamber.
The pacemaker helps regulate this electrical system. If the heart is not able to send the correct electrical signals, due to a blockage or heart disease, it can cause bradycardia.
Complete heart block is a type of electrical issue that makes it impossible for electrical signals to travel from the atria the top two chambers of the heart to the ventricles, which are the bottom two chambers. In complete heart block, the top two chambers may have totally different rhythms to the bottom two.
Vasovagal Syncope As A Cause Of Dizziness
Vasovagal syncope is a common cause of dizziness, lightheadedness, and fainting. The vagus nerve is overstimulated and causes the bodys blood vessels to dilate and the heart to slow down. This anti-adrenaline effect decreases the ability of the heart to pump blood upward toward the brain. Without blood flow, the brain turns off. In Victorian England, young ladies sensibilities were easily offended causing a vasovagal episode called a swoon.
Some people faint at the sight of blood. Some parents faint when their child gets immunized. Some medical students faint at their first autopsy. Many types of emotional and physical stressors can overstimulate the vagus nerve, causing dizziness, lightheadedness, and at times fainting .
Fainting is not normal. If a person is unconscious, activate the emergency medical system , and seek medical care.
What Causes Elevated Heart Rate And Dizziness
Dizziness. A high heart rate can make you feel suddenly dizzy. When your heart beats faster than it should, it will pump more blood. If blood is rushing to your brain, it can make you feel lightheaded and dizzy. Vertigo is another common problem associated with tachycardia , according to MedlinePlus .
What Procedures And Tests Diagnose Low Blood Pressure
In some people, particularly relatively healthy ones, symptoms of weakness, dizziness, and fainting raise the suspicion of low blood pressure. In others, an event often associated with low blood pressure, for example, a heart attack, has occurred to cause the symptoms.
Measuring blood pressure in both the lying and standing positions usually is the first step in diagnosing low blood pressure. In patients with symptomatic low blood pressure, there often is a marked drop in blood pressure upon standing, and patients may even develop orthostatic symptoms. The heart rate often increases. The goal is to identify the cause of the low blood pressure. Sometimes the causes are readily apparent . At other times, the cause may be identified by testing:

High Blood Pressure and Dizziness
Dizziness is one of the most common symptoms that will prompt an individual to visit a doctor. The term dizzy can be difficult to define because it can mean different things to different people. Does feeling dizzy refer to lightheadedness, the feeling of weakness and almost passing out, or does it refer to vertigo ? Dizziness is one of the symptoms of chronic high blood pressure is dizziness, in addition to headache, blurred vision and fatigue.
- Management of diabetes, such as regular insulin injections
- Changes in medication or altered doses if drugs are the cause
- Medication, surgery or both to treat heart conditions
- Medication to increase blood volume or pressure, including corticosteroids
- Medications to treat orthostatic hypotension including pyridostigmine, a drug used in the treatment of myasthenia gravis
- A range of treatments, since orthostatic hypotension may have two or more causes
- In some cases, a lower body pressure suit is required.
How Does Blood Pressure Work
During relaxation of the heart , the left ventricle of the heart fills with blood returning from the lungs. The left ventricle then contracts and pumps blood into the arteries . The blood pressure in the arteries during contraction of the ventricle is higher because blood is being actively ejected into the arteries. It is lower during relaxation of the ventricle when no blood is being ejected into the arteries. The pulse we feel when we place our fingers over an artery is caused by the contraction of the left ventricle and the ejection of blood.
Blood pressure is determined by two factors:
Generally, blood pressure tends to be higher if more blood is pumped into the arteries or if the arterioles are narrow and/or stiff. Narrow and/or stiff arterioles, by resisting the flow of blood, increase blood pressure. Arterioles may become narrower when the muscles surrounding them contract. Arterioles may become stiff and narrow when older patients develop atherosclerosis.
Blood pressure tends to be lower if less blood is being pumped into the arteries or if the arterioles are larger and more flexible and, therefore, have less resistance to the flow of blood.
The heart rate increases and the forcefulness of the heart’s contractions increase, pumping more blood through the heart.

Who Should Avoid Taking Metoprolol
Certain groups of people should avoid using metoprolol or use it with caution :
- People with asthma: Metoprolol may trigger an asthma attack, and people with asthma or COPD should avoid using it. Make sure your healthcare provider is aware that you have asthma before starting metoprolol.
- People with diabetes: Metoprolol can block the signs of low blood sugar, like increased heart rate, sweating, and tremors.
- People with a slow heart rate or low blood pressure : Metoprolol lowers blood pressure and heart rate.
- Pregnant women: The U.S. Food and Drug Administration has deemed metoprolol as pregnancy category C this means that there is not enough information to determine the risk to the pregnancy . Women and their healthcare providers should weigh the benefits of taking metoprolol against the risk to the fetus.
- Nursing mothers: Metoprolol does get into the breastmilk, in small quantities, and no adverse effects have been reported. Women and their healthcare providers should weigh the risks and benefits of the medication .
- People with liver disease: Since metoprolol is broken down by the liver, people with liver disease may have higher than expected levels of metoprolol in their system. They may need a lower dose of metoprolol .
This list does not include all possible at risk groups and others may exist. Check with your pharmacist or healthcare provider for more information.
Whats The Difference Between Blood Pressure And Pulse
Blood pressure and pulse are two measurements that a doctor may use to monitor your heart and overall health. While theyre similar, they can each say very different things about whats happening in your body.
Pulse, also called heart rate, refers to the number of times your heart beats in one minute. Typical pulse measurements range from 60 to 100 beats per minute.
Blood pressure is an estimate of the force your blood is exerting on your blood vessels. A typical value for blood pressure is 120/80. Doctors consider blood pressure to be elevated when its between 130 and 139 systolic over 80 to 89 diastolic .
If you have high blood pressure with a low pulse, it means your blood is putting increased pressure on your blood vessels, but your hearts beating fewer than 60 times per minute. Read on to learn more about what this combination means for your health.

What Are The Symptoms Of Having A Low Red Blood Cell Count
A low red blood cell count, most often referred to as anemia, can cause weakness, fatigue, dizziness, fainting, lack of energy, pale skin, rapid heart rate or palpitations and shortness of breath. Chronic anemia in children may cause learning problems and increased risk of infection, says MedicineNet
The symptoms of slowly developing anemia include headaches grumpiness feeling of weakness or tiredness and problems thinking or concentrating. As the condition worsens, the range of symptoms widens to include pale skin, brittle nails, sore tongue, shortness of breath, dizziness upon standing, bluish color in the whites of the eyes and cravings for ice or nonfood items. Different forms of anemia can cause additional or other symptoms, explains MedlinePlus.
The onset of anemia may be the result of taking certain medications, pregnancy or red blood cells being destroyed sooner than normal. Chronic diseases that can cause anemia include cancer, rheumatoid arthritis, chronic kidney disease or ulcerative colitis. Bone marrow disorders that may cause anemia are leukemia, multiple myeloma, lymphoma, aplastic anemia or myelodysplasia. Some types of anemia may be inherited, according to MedlinePlus.
