If You Notice A Sudden Decline In Blood Pressure
A single lower-than-normal reading is not cause for alarm, unless you are experiencing any other symptoms or problems. If you experience any dizziness, lightheadedness, nausea or other symptoms, its a good idea to consult with your healthcare provider. To help with your diagnosis, keep a record of your symptoms and activities at the time they occurred.

How Does The Body Maintain Normal Blood Pressure
Baroreceptors are small nerve cells within arteries close to the heart that help regulate blood pressure. Baroreceptors communicate with the kidneys, arteries, veins, and heart to increase, decrease, or maintain blood pressure, as needed. The function of the baroreceptors is to ensure that sufficient blood reaches the organs and tissues of the body.
The Squeeze / Pressure In The Carotid Sheath
The carotid sheath is in the front and on both sides of our neck. It lays close to your styloid process which connects to your hyoid bone and also to the anterior lateral part of your C1 or the first bone in your neck. If there is compression in this area, then the blood pressure is going to be off, and in some cases roller coaster.
We are going to refer to our article;Cervical spine compression causes internal jugular vein stenosis for a summary understanding of compression to the carotid sheath, artery, and jugular vein.

Medications That Can Cause Low Blood Pressure
Several medicines may cause low blood pressure, including some medications used to control high blood pressure.
Working with your doctor or other health care provider to change your medication or adjust your dosage can help control low blood pressure. You should never modify a dose or stop taking a medication without first consulting your health care provider.
Alpha and beta blockers, diuretics, erectile dysfunction drugs, Parkinsons disease drugs and some types of antidepressants can cause low blood pressure.
Medications that can cause low blood pressure include:
- Benicar a prescription blood pressure medication
- Cialis an erectile dysfunction drug; risk is especially high when taken with nitroglycerin heart medication
- Cymbalta a serotonin and norepinephrine inhibitor antidepressant
- Hydrochlorothiazide a widely used generic diuretic
- Inderal, Innopran XL and other versions of propranolol beta blockers
- Lasix a diuretic
Atrial Fibrillation Won’t Cause Heart Attack But Can Lead To Other Serious Complications
I suffer from atrial fibrillation. Are my chances of getting a heart attack higher?
Your risk of a heart attack is not increased due to atrial fibrillation, a rapid and irregular heartbeat that can cause symptoms requiring medical attention. The condition does not cause a heart attack. However, atrial fibrillation can lead to other serious complications, so it needs to be treated promptly and monitored closely.
During atrial fibrillation, the heart’s two upper chambers beat chaotically and irregularly, out of coordination with the two lower chambers . Because of the uncoordinated heartbeat it produces, atrial fibrillation causes your heart to pump less effectively than normal. The result is that the heart sends less blood out to your body with each beat. This can cause a variety of symptoms, including decreased blood pressure, light-headedness, weakness and shortness of breath.
Occasionally, the rapid heart rate associated with atrial fibrillation can result in chest pain or discomfort because of reduced blood flow to the heart muscle. People who have pre-existing heart disease are particularly susceptible to this symptom of atrial fibrillation. Angina can be hard to distinguish from other types of chest pain, so if you experience chest pain, it is important to seek medical attention right away.
Talk to your doctor about the risks associated with atrial fibrillation and what you can do to reduce those risks.

What Are The Symptoms Of Heart Failure
There may be times that your symptoms are mild or you may not have any symptoms at all. This doesn’t mean you no longer have heart failure. Symptoms of heart failure can range from mild to severe, and may come and go.
In general, heart failure gets worse over time. As it worsens, you may have more or different signs or symptoms. It is important to let your doctor know if you have new symptoms or if your symptoms get worse.
What Blood Pressure Readings Mean
Blood pressure readings are measured in millimeters of mercury and are written as systolic pressure — the force of the blood against the artery walls as your heart beats — over diastolic pressure — the blood pressure between heartbeats.
People with ideal blood pressure will have readings below 120 over 80, expressed as 120/80. About 1 in 3 U.S. adults have high blood pressure, the American Heart Association says.

Dad Died Of A Heart Attack At 58 So I Was High Risk
For 55-year-old Jill Stevenson from Ayrshire, taking a daily pill to reduce her shockingly high levels is a non-event.
The journalist prided herself on her blood pressure readings for the best part of a decade until, during a spot check-up before enrolling in medical research, it read 180 over 100.
Ive had annual blood pressure readings every year for about ten years because of other medication I take, and its always been fine, she says.
Im sure it was the menopause that sent things haywire.
Jills GP advised her to lose weight, do more exercise and monitor her blood pressure at home using a DIY kit.
She was also referred to a cardiologist for further tests.
I really didnt want to go on pills, says Jill.
I thought Ill get myself healthier, lose the 10 lb. I knew I should probably shift and start walking a bit more.
But when results from a heart scan showed a slight abnormality in her beating pattern, she went back to the GP and asked for medication, and was prescribed a 5mg daily dose of diuretic, which was increased to 10mg a few weeks later.
Perhaps, Jill says, she ought to have been taking them years ago even when her blood pressure was healthy.
I was at high risk of having a heart attack or stroke but had no idea.
Especially as my father died from a heart attack aged 58, and both my mother and my brother are on pills for high blood pressure.
She now says that taking the medication has been more than worth it.
A Lot Of Diagnoses A Lot Of Misunderstanding
A June 2020 paper in the Journal of Atrial Fibrillation , describes the lesser-known diagnoses of a racing heart and the problem of heart rate messaging miscommunication in the autonomic nervous system.
The cardiovascular branch of the autonomic nervous system is responsible for the regulation of heart rate, blood pressure, and maintaining homeostasis during physiological stress such as exercise and standing upright. The autonomic nervous system constantly controls the rate and force of heart contractions and the vascular tone with the aim to maintain the sufficient tissue perfusion with oxygenated blood and secure venous return to the heart. .
- Dysautonomia ;;problems of or dysfunction of the autonomic nervous system.
Dysautonomias, the result of an autonomic nervous system malfunction, is often found in patients with cardiovascular symptoms. Apart from the most prevalent one, arterial hypertension , the cardiovascular dysautonomic continuum encompasses other important although less known conditions: postural orthostatic tachycardia syndrome, inappropriate sinus tachycardia, orthostatic hypotension and reflex syncope . Moreover, heart diseases may evoke autonomic imbalance by themselves; cardiac pump failure is usually associated with sympathetic hyperactivity , neuroendocrine vasopressor activation , higher heart rate, reduced heart rate variability and baroreflex hyposensitivity , all of which are predictors of adverse outcomes.

Low Blood Pressure Anxiety And More Hyperventilation
There are two factors that tend to contribute to the extent to which this drop in blood pressure occurs.
- First, when a person hyperventilates, signals are sent to the body that it is not getting enough air, even though, in reality, it is getting too much. This tends to cause people to try to yawn or take deeper breaths, and unfortunately, this ends up making hyperventilation worse, and causing a further drop in blood pressure.
- Second, hyperventilation and low blood pressure cause several symptoms that can worsen anxiety, and thus, worsen hyperventilation. When a person has low blood pressure, the heart beats faster and harder to compensate. This may cause a person to experience chest pains, and contribute to feelings of lightheadedness and dizziness. People may feel as though they may faint, and in some cases, this could occur. All of these physical symptoms can increase anxiety, increase hyperventilation, and continue to sustain a lower blood pressure.
In nearly all of these cases, the change in blood pressure tends to be temporary. Once a person is able to regain control of his or her breathing, the blood pressure levels should go back to normal. Sometimes, regaining control of breathing can take longer than other times.
Patients Who Present In The Emergency Room With Chest Pain Are Given A Troponin Test
Troponin is a protein enzyme that leaks from the heart when this muscle is damaged.
If the test result is elevated , this can mean that the patient had a heart attack very recently.
However, elevated troponin doesnt always mean cardiac damage.
In fact, the test result isnt either normal or elevated; there is another range an in-between range.
Its sometimes referred to as a gray area or indeterminate area, which warrants a follow-up blood draw several hours later to see if the result is of a higher value .

Your Mysterious Symptoms And Cervical Spine Problems
Heart Rate Variability has become a new and popular subject for longevity experts and advanced sports science. Simply if your heart is always racing, doesnt rest, if it does not have slow beats with consistent heart rate variable, you are at higher risk for disease and premature death from cardiovascular events. This is not the subject of this article. This article deals with your mysterious symptoms, like those explained above. Dizziness, balance issues, panic attacks, loss of consciousness, possible problems with digestion, breathing, headaches, and other possible problems caused by cervical spine instability pressing on the vagus and cervical nerves.
The stories of racing hearts
I had bulging discs up and down my neck. But it is not significant enough to operate on. For now, I would just have to manage along with my neck pain, shoulder pain, and if my heart raced, I should find a quiet place to rest and avoid caffeine and sugary food.
I have been having neck and shoulder pain going on for one year now. I am young, 25, athletic, do a lot of working out in the gym. I woke up one morning, my arm left arm was numb and I had significant shoulder pain. I thought I slept on it wrong, but the numbness persisted, the pain came and went. After a few weeks, I went to the doctor, had an MRI. The doctor said, nothing wrong here, and that I should come back if things did not get better on their own.

How Do I Know If I Have High Blood Pressure
Theres only one way to know if you have high blood pressure: Have a doctor or other health professional measure it. Measuring your blood pressure;is quick and painless.
Talk with your health care team about regularly measuring your blood pressure at home, also called self-measured blood pressure monitoring.
High blood pressure is called the silent killer because it usually has no warning signs or symptoms, and many people do not know they have it.
Low Diastolic Pressure: No Symptoms
“When your systolic blood pressure gets too low, it can manifest as lightheadedness, fainting, and weakness. But low diastolic pressure by itself doesn’t have any symptoms,” says Dr. Paul Conlin, professor of medicine at Harvard Medical School and chief of medicine at the VA Boston Healthcare System.
One of the new studies, which analyzed the medical records of more than 11,000 adults over a period of three decades, found that people who had low diastolic blood pressure were twice as likely to have subtle evidence of heart damage compared with people whose diastolic blood pressure was 80 to 89 mm Hg. Low diastolic values were also linked to a higher risk of heart disease and death from any cause. The findings appeared in the Aug. 30, 2016, Journal of the American College of Cardiology.
Another study, published in The Lancet, involved more than 22,000 people with heart disease, whom researchers grouped according to their blood pressure readings. People with well-controlled blood pressure values were considered the reference group.
Not surprisingly, people with high systolic blood pressure were more likely to experience heart attacks or strokes, be hospitalized with heart failure, or to die compared with people in the reference group. But the same was true for heart attacks, heart failure, and death in people with low blood pressure .

How Is Blood Pressure Determined
Several factors influence blood pressure. Blood volume and blood vessel wall behavior are two important determinants of blood pressure. The more blood pumped with each heartbeat, the higher the blood pressure. The presence of stiff or narrow artery walls that resist blood flow also increases blood pressure. Having lower blood volume and open, flexible arteries decreases blood pressure.
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.

Lack Of Oxygen In The Blood
If levels of oxygen in the blood decrease due to carbon monoxide poisoning or a loss of normal lung function, the heart will receive un-oxygenated blood.
This will result in the heart muscles being damaged, triggering a heart attack.

Stages C And D With Preserved Ef
Treatment for patients with Stage C and Stage D heart failure and reserved EF includes:
- Treatments listed in Stages A and B.
- Medications for the treatment of medical conditions that can cause heart failure or make the condition worse, such as atrial fibrillation, high blood pressure, diabetes, obesity, coronary artery disease, chronic lung disease, high cholesterol and kidney disease.
- Diuretic to reduce or relieve symptoms.
YOU ARE THE MOST IMPORTANT PART OF YOUR TREATMENT PLAN!
It is up to you to take steps to improve your heart health. Take your medications as instructed, follow a low-sodium diet, stay active or become physically active, take notice of sudden changes in your weight, live a healthy lifestyle, keep your follow-up appointments, and track your symptoms. Talk to your healthcare team about questions or concerns you have about your medications, lifestyle changes or any other part of your treatment plan.

What Are The Symptoms Of Low Blood Pressure
Low blood pressure often has no symptoms, but can sometimes mean that not enough blood is flowing to your brain or organs. This can cause symptoms such as:
- feeling dizzy, faint or light-headed
- feeling unsteady
- suddenly noticing your heartbeat
If you have these symptoms, stop what youre doing and sit down or lie down in case you fall, and drink some water.
Speak to your doctor or nurse if you experience these symptoms. As well as being unpleasant, they could mean youre at risk of having a fall. They could also be a sign of another health problem.
