What Is A Normal Heart Rate
A normal resting heart rate is usually between 60 and 100 beats per minute. Your number may vary. Children tend to have higher resting heart rates than adults.
The best time to measure your resting heart rate is just after you wake up in the morning, before you start moving around or have any caffeine.
Nutrients Involved In Cardiovascular Health
Many of the foods you consume help support your cardiovascular health. These foods contain essential nutrients that can help regulate your blood pressure, maintain normal heart rhythm and support other aspects of healthy heart function.
According to the Food and Drug Administration, foods with potassium and magnesium are beneficial to your cardiovascular health. Both of these essential nutrients regulate blood pressure and maintain normal heart function. Sodium and vitamin D can also influence your blood pressure.
Sodium, in particular, is a nutrient to watch out for. According to the American Heart Association, most people consume too much sodium each day. Instead of consuming the recommended 1,500 to 2,300 milligrams per day, the average American consumes 3,400 milligrams of sodium on a daily basis.
Excessive sodium consumption is widely known to increase your blood pressure and be bad for your cardiovascular health. In turn, reducing your sodium intake lowers your blood pressure. However, according to a March 2016 study in the journal Frontiers in Physiology, lowering your sodium consumption also increases your heart rate.
You should talk to your doctor or nutritionist before making any major dietary changes like drastically reducing your sodium intake. While an increase in heart rate may be a nonissue for healthy people, it can be dangerous for people who have pre-existing cardiovascular issues.
Whats A Normal Heart Rate
A heart rate is a measurement of the number of times the heart muscle beats per minute. Healthy kids and adults will have hearts that beat at different speeds because of their age and body size. If the heart is beating too fast or too slow, this could mean you have an underlying health problem. Your resting heart rate will also allow you to gauge your current heart health.
In general, a lower resting heart rate means the heart is beating less per minute, which likely means its more efficient. Your resting heart rate tells you how fast your heart is beating when youre in a relaxed state, like sitting or laying down. If your resting heart rate is too high, this might mean you have lower physical fitness, or that youre at risk of developing a heart condition.
Knowing what your target heart rate should be for your age can help you recognize if and when your heart rate is abnormal, which may be an indication that its time to go to the doctor.
| Normal heart rate by age | |
|---|---|
| Age | |
| 18 and older | 60-100 bpm |
As we get older, the range of whats considered to be a healthy normal resting heart rate will change.
The average healthy adult will have a resting heart rate of 60 bpm or higher. Although in clinical practice, the resting heart rate between 60 and 100 bpm is considered to be normal, people with a resting heart rate higher than 80 bpm could have an increased risk of developing cardiovascular disease.

How To Lower Your Resting Heart Rate
In general, people who are more fit and less stressed are more likely to have a lower resting heart rate. A few lifestyle changes can help you slow it down:
- Exercise regularly. It raises your pulse for a while, but over time, exercise makes your heart stronger so it works better.
- Eat right. Losing weight may slow your resting heart rate. And studies have found lower heart rates in men who eat more fish.
- Tackle stress. Set aside time to disconnect from electronic devices and relax each day. Meditation, tai chi, and breathing exercises can also help.
- Stop smoking. Itâs one of the best things you can do for your overall health.
How Is Inappropriate Sinus Tachycardia Diagnosed
Your healthcare provider will review your health history and do a physical exam. He or she can easily notice a fast heartbeat by taking your pulse. But, it is important to rule out other causes for the fast heartbeat. It is also important to learn what type of tachycardia is present. Other types of tachycardia may need different treatment.
Your healthcare provider might use tests to help make this diagnosis. These include:
- Electrocardiogram, to analyze the hearts electrical rhythm and the type of tachycardia
- Continuous monitoring of the heart rhythm , to check the rhythm for a longer period of time
- Blood tests, to look for other causes of the fast heartbeat
- Echocardiogram, to check the fluid around the heart and heart motion
- Chest X-ray, to view the heart and lungs
IST is sometimes diagnosed in error as an anxiety disorder.

What Causes Ventricular Tachycardia
Your heart rate is controlled by electrical signals that move across the heart muscle. When something goes wrong and signals are sent too quickly, it can cause tachycardia. Most patients with ventricular tachycardia have another heart problem, such as coronary artery disease, high blood pressure, an enlarged heart or heart valve disease. The condition can also develop after a heart attack or heart surgery because of scar tissue that forms on the heart. Other, non-heart-related causes of ventricular tachycardia include some medications, an imbalance in electrolytes , too much caffeine or alcohol, recreational drugs, exercise, and certain genetically transmitted conditions. Sometimes the cause is unknown. You are also more likely to have ventricular tachycardia as you get older or if you have a family history of heart rhythm disorders.
Reason Of Slow Heart Rate
A heart that beats less than 60 times in a minute is called Bradycardia. Though considered common and healthy for adults, it is a serious heart disease and if not diagnosed on time can lead to serious heart ailments.
Types of Bradycardia
- Sinus pause: Also called Sinus Arrest, under this, the heart skips one beat.
- Sinus Bradycardia: It is common and not a serious issue as the heart beats less than 60 times in a minute.
- Sick Sinus Syndrome: When the pacemaker of our heart does not work properly, several irregular heart rates can take place.
- Tachy-Brady Syndrome: Due to damage pacemaker of the heart, the heartbeat is usually too fast or slow.
Symptoms and Causes of Bradycardia:
Heart gets damaged due to various causes like as below:
- Side-effects of medication,
- Fainting and tired most of the time,
- Lack of energy due to which hard to do any physical exercise

Treatment Of Fast Heart Rate
Treat the Underlying Cause: Most important is to ensure there is no underlying systemic problem that is causing the fast heart rate. If there is anemia, for example, that will need to be treated. Infection and dehydration would need to be treated. Hormonal imbalances would require treating. Medications will be reviewed and any potential offending agents will need to be stopped if possible.
Medications: It is important not just to treat a number the reason underlying must be sought out. If the fast heart rate is thought to be from a cardiac cause then the appropriate treatment should be given. If there is significant muscle dysfunction then treatment aimed at strengthening the heart is given. If there are problems with the electrical system of the heart then medicines to slow the rate may be given such a beta blockers or calcium channel blockers. In some cases stronger medicines that prevent the occurrence of the arrhythmia in the first place may be prescribed, known as anti-arrhythmic medications. Specialists known as electrophysiologists typically prescribe anti-arrhythmic medications.
How To Treat A Fluctuating Heart Rate
Most of the time, a fluctuating heart rate â whether it’s too fast or too slow â will fix itself.
If it’s caused by an underlying condition, though, treating the condition can help stabilize your pulse. For example, your doctor might prescribe iron supplements if you have anemia, or medication to correct a thyroid disorder.
Arrhythmias are more complex and require a complete work-up by a cardiologist, but those can usually be managed with lifestyle changes or medications.
You should seek medical help right away if you feel chest pain, high heart rate at rest or shortness of breath out of proportion to what would be expected for the degree of activity, says Dr. Arora. “Chest pain associated with sweating and nausea is particularly concerning, as that can be due to a heart attack,” he adds.
Other red flags can include feeling weak, dizzy or lightheaded.

Is A Heart Attack More Likely After Covid
That depends: Post says that heart attack has several different forms. A type 1 heart attack, caused by a blood clot blocking one of the hearts arteries, is rare during or after COVID-19 infection.
Type 2 heart attacks are more common with COVID-19, she says. This heart attack can be caused by increased stress on the heart, such as a fast heartbeat, low blood oxygen levels or anemia, because the heart muscle isnt getting enough oxygen delivered in the blood in order do this extra work. We have seen this in people with acute coronavirus disease, but it is less common in those who have survived the illness.
Blood tests have shown that during COVID-19, some people have elevated levels of a substance called troponin in their blood, along with EKG changes and chest pain. Elevated troponin levels are a sign of damaged heart tissue. Sometimes this is from a heart attack. This is less commonly seen after COVID-19.
During acute COVID-19, elevated troponin levels with an abnormal EKG are linked to higher mortality, but not in patients with a normal EKG, Post says.
When To Call Your Doctor
If youre on a beta blocker to decrease your heart rate or to control an abnormal rhythm , your doctor may ask you to monitor and log your heart rate. Keeping tabs on your heart rate can help your doctor determine whether to change the dosage or switch to a different medication.
If your pulse is very low or if you have frequent episodes of unexplained fast heart rates, especially if they cause you to feel weak or dizzy or faint, tell your doctor, who can decide if its an emergency. Your pulse is one tool to help get a picture of your health.

Why Is My Resting Heart Rate Decreasing
As mentioned above, a low resting heart rate is often a sign that youre in peak physical fitness. However, in some cases, a low RHR could cause you to feel dizzy or exhausted. If youre experiencing these symptoms and are wondering why is my resting heart rate going down, then you should speak to a doctor. Its also good to remember that medications like beta-blockers are designed to slow your pulse down as they block adrenaline. So always be mindful of what prescription drugs you are taking and how they could be affecting your RHR.
What Is Ventricular Tachycardia
The ventricles are the hearts two lower chambers. Blood flows from the top chambers of the heart into the ventricles, then it moves to the lungs and through the aorta to be circulated throughout the body. Tachycardia is a heart rate higher than 100 beats per minute. A normal resting heart rate is 60 to 100 beats per minute. Ventricular tachycardia starts in the hearts lower chambers. Most patients who have ventricular tachycardia have a heart rate that is 170 beats per minute or more.

Why Your Heart Rate Increases When You Exercise
If you have ever exercised in your life, are an athlete, or visit the gym daily, then you would have noticed your heart rate increasing while you exercise. Even when you stop your exercise, the heart rate doesnt return to normal immediately. Some may be worried about it, but the truth is, most of the time you don’t have to.
Your Thyroid Is In Overdrive
Your thyroid gland produces various hormones, like thyroxine and triiodothyronine, which affect a ton of your bodys systems, according to the Mayo Clinic. If you have hyperthyroidism, your thyroid is overactive and produces too much thyroxine, which in turn speeds up your bodys metabolism too much. This can result in a rapid or irregular heartbeat, along with symptoms like an increased appetite and sudden weight loss. There are plenty of medications out there to treat hyperthyroidism, including beta blockers to specifically address your quick heart rate.

Supraventricular tachycardia is the most common pathologic rhythm disturbance in children, with an estimated prevalence of 1 to 250 per 25,000 children. Eighty percent of cases present in children younger than 1 year old. SVT is characterized by an abnormally rapid heart rate that originates above the ventricles.
When To See A Doctor
A person experiencing a fast heart rate should take special note of whether or not he is experiencing additional symptoms. Are there are other things going on that could be making someone feel lousy?
For example, a person who is experiencing shortness of breath, activity intolerance, palpitations, or extreme fatigue should see a doctor immediately.
Its important to note that many people who are experiencing an elevated heart rate dont feel it or associate it with other issues. In other words, it can often take a bit of an investigation to discover the cause.

Shortness Of Breath Or Chest Pain After Covid
Shortness of Breath
You want to consult a doctor if any of your symptoms are severe, especially shortness of breath, Post says. She recommends using a commercially available O2 saturation monitor.
Shortness of breath by itself is not always a sign of a serious problem, but if you have that symptom along with low O2 , that is a reason to be concerned. Sometimes people are short of breath with exertion after COVID-19 because they have been less active for a long time and need to gradually build their fitness level back up.
COVID-19 Chest Pain
What about lingering chest pain, another common post-COVID complaint? Chest pain may be nothing serious, but if you are having severe chest pain, get help, especially if it is persistent or if you are also having nausea, shortness of breath or lightheadedness: These could be symptoms of a heart attack.
If you have chest pain when you inhale, you might have lung inflammation. Sudden, severe chest pain could be a blood clot in the lung , Post says.
Family doctor or cardiologist?
If your symptoms are not severe but you want to be checked out, Post says a cardiologist doesnt need to be your first stop if youve never had heart problems before and are not at risk. For nonemergency post-COVID-19 symptoms, your primary care practitioner can advise you, she says.
Heart Failure and COVID-19
- Shortness of breath, especially with exertion
- Fatigue
- Shortness of breath when lying down
- Leg swelling

When Changes In Heart Rhythms Warrant A Physicians Attention
Though most fluctuations in heart rhythms will likely be harmless, there are times your first response should be to seek medical advice.
- Your symptoms are sudden and abnormal. If theres a clear first time that you notice a rhythm change in your heart, its a good idea to alert your doctor, Anderson says. You should also call your doctor when a change in heart rhythms corresponds to chest pain, losing consciousness or a prolonged sense that you might pass out. Likewise, contact a medical professional if a rhythmic abnormality persists.
- Your history involves other heart issues. If you were born with a malformation if youve had heart surgery if youve had a heart attack or long-standing, untreated high blood pressure or if there is something otherwise abnormal with your heart and you notice abnormal heart rhythms, you should see your doctor.
- Your family history puts you at increased risk. Your doctor may ask you to attend more closely to changes in your heart rhythms if your family has a history of heart disease or sudden death.

Causes Of Supraventricular Tachycardia
An episode of supraventricular tachycardia occurs when abnormal electrical impulses suddenly start in the upper chambers of the heart, and override the heart’s natural rhythm.
SVT is sometimes called paroxysmal supraventricular tachycardia . Paroxysm means a sudden temporary disturbance of heart rhythm.
PSVT is usually caused by a short circuit in the electrical system of the heart, which causes an electrical signal to travel rapidly and continuously around in a circle, forcing the heart to beat each time it completes the circuit.
Another type of SVT is called Wolff-Parkinson-White syndrome, where an abnormal electrical connection occurs between the atria and ventricles . People with Wolff-Parkinson-White syndrome are born with a strand of extra muscle tissue between these chambers. This produces a short circuit, which causes the fast heartbeat.
What Is A Normal Resting Heart Rate
For a well-trained athlete, their resting heart rate will usually be around 40 beats per minute.
For adults, a normal RHR ranges from 60 to 100 beats per minute, although most people who are relaxed and healthy should be below 90. For a well-trained athlete, their RHR will usually be below this, around 40 beats per minute. This is because a lower RHR is often a sign of good cardiovascular fitness and efficient heart function.
However, you shouldnt compare your RHR with someone elses. Youre unique and beautiful and thats how it should be. While your neighbors RHR might be lower than yours, it might be for a dozen different reasons.
Instead of comparing yourself to others, youre better off monitoring how your RHR is changing over time. When your resting heart rate decreases as a result of training, its a sign that your aerobic fitness has improved.
Take that, neighbor.
