Is a heartbeat of 43 beats per min too slow?

Question

and not athlete thanks

Answer 1

Yes it is too slow. Normal Heart Beat for adult ranges from 60-100 beats per min. It is called bradycardia.

Bradycardia is an abnormally slow heart rate of less than 60 beats per minute. A normal heartbeat is between 60 and 100 beats per minute.
Here's what happens during a normal heartbeat: The electrical signal that starts a heartbeat comes from the heart's sinus node, the natural pacemaker located in the upper portion of the right atrium. From the sinus node, the heartbeat signal travels to the atrioventricular (A-V) node, located between the atria, and then through the bundle of His (pronounced "hiss") — a series of modified heart-muscle fibers located between the ventricles to the muscles of the ventricles. This triggers a contraction of the ventricles and produces a heartbeat.

Bradycardia, even as low as 50 beats per minute, can be normal in athletes and other people who are physically active. In these people, regular exercise improves the heart's ability to pump blood efficiently, so fewer heart contractions are required to supply the body's needs.

In other cases, bradycardia can be a form of cardiac arrhythmia, a heart-rate abnormality. Cardiac arrhythmia can be caused by a problem in the sinus node, or it can be related to some disturbance in the passage of heartbeat signals through the A-V node and bundle of His. Also, bradycardia sometimes is a side effect of certain medications, including propranolol (Inderal), atenolol (Tenormin), metoprolol (Toprol-XL), sotalol (Betapace), verapamil (Calan, Isoptin, Verelan) and diltiazem (Cardizem, Dilacor-XR). Bradycardia also occurs in some people who have certain medical illnesses not related to the heart, such as:

Abnormally low level of thyroid hormones (hypothyroidism)
Severe liver disease
An abnormally low body temperature (hypothermia)
Typhoid fever
Brucellosis, an infectious disease marked by fever, sweating and weakness that is transmitted to humans by direct contact with diseased animals or through ingestion of contaminated meat, milk or cheese

Symptoms

Bradycardia can cause dizziness, weakness, lack of energy, or fainting spells.
If bradycardia is caused by a medical illness, there will be additional symptoms that are specific to that illness. For example, people whose bradycardia is due to severe hypothyroidism also can have constipation, muscle cramps, weight gain (often despite poor appetite), very dry skin, hair that is thin and dry, an abnormal sensitivity to cold temperatures and other symptoms related to low levels of thyroid hormones.

Diagnosis

Your doctor will ask about your family history of heart disease, cardiac arrhythmias and fainting spells. He or she also will review your current symptoms and your personal medical history, including your use of medications that may cause bradycardia.
During the physical examination, your doctor will check your heart rate and rhythm, and your pulse. You may be asked to do some sit-ups or other exercise so that your doctor can see if your heart rate rises normally when your heart is asked to do more work. Your doctor also will check for physical signs of thyroid abnormalities, including an enlarged thyroid gland, very dry skin, and hair that is thin and dry.

To further evaluate your bradycardia, your doctor will order an electrocardiogram (EKG). However, because some forms of bradycardia come and go, a one-time office EKG may be normal. If this is the case, a test called ambulatory electrocardiography may be done. During this test, the patient wears a portable EKG machine called a Holter monitor, usually for 24 hours. If your symptoms are infrequent, you may wear a monitor for longer. You will be taught to press a button to record your EKG reading when your symptoms occur.

Depending on the results of your physical examination, other tests may be necessary to check for medical illnesses that produce bradycardia. For example, if you have symptoms and physical signs of hypothyroidism, your doctor may order blood tests to measure levels of thyroid hormones and TSH, a pituitary gland hormone that stimulates the thyroid. Your doctor also may order blood tests for cholesterol and certain liver enzymes, which often are elevated in people with hypothyroidism.

Expected Duration

How long bradycardia lasts depends on its cause. For example, normal bradycardia in a well-trained athlete will last as long as the athlete maintains his or her usual level of exercise. When bradycardia occurs as a side effect of medication, it usually will go away as soon as the drug that triggered the bradycardia is used by the body or excreted in the urine. Bradycardia caused by hypothyroidism will go away quickly after treatment with thyroid hormones. Certain forms of bradycardia resulting from cardiac arrhythmias can be cured with a permanent pacemaker.


Prevention

There are no general guidelines to prevent all forms of bradycardia. When bradycardia occurs as a side effect of medication, the problem can be prevented by either switching the drug or reducing its dose.

Treatment

In most cases, bradycardia in healthy, well-trained athletes does not need to be treated. In fact, in most people, bradycardia does not require treatment unless patients have symptoms that are clearly due to a slow heartbeat. The following are conditions that produce bradycardia that requires treatment:


Cardiac arrhythmias resulting from sinus-node dysfunction — In people with frequent, severe symptoms of sinus-node dysfunction, the main treatment is usually a permanent pacemaker, an implanted device that generates electrical impulses to regulate the heartbeat.


Cardiac arrhythmias resulting from A-V node problems — In people with A-V node problems, the passage of heartbeat signals may be blocked to different degrees. Some patients with less severe degrees of A-V block do not need treatment. Others may simply be monitored with frequent EKGs, especially if they don't have any symptoms and have a heart rate that is adequate for their daily activities. People with the most severe form of A-V block (called third-degree A-V block) can be treated with a special dual-chambered permanent pacemaker, a pacemaker with one electrode in the atrium and one in the ventricle.


Hypothyroidism — Hypothyroidism is treated with replacement doses of thyroid hormones. Synthetic forms of these hormones are available — llevothyroxine (Synthroid, Levothroid and others), liothyronine (Cytomel, Triostat) or liotrix (Thyrolar) — as well as thyroid extract.

When To Call A Professional

Call your doctor if your pulse is less than 60 beats per minute. This is especially important if you have had dizziness, weakness, lack of energy or fainting spells.


Prognosis

In well-trained athletes with normal bradycardia, the slow heartbeat is often a sign of overall good health. In other people with bradycardia, the outlook depends on the underlying disorder. For example, the prognosis is usually good in people with hypothyroidism, since treatment with thyroid hormones can relieve bradycardia and other symptoms related to low hormone levels. In some elderly patients, hormone dosages may need to be increased very slowly over several weeks to prevent straining the heart. At one time, the prognosis for people with third-degree A-V block was poor, with 50% of patients dying within one year of diagnosis. Now, however, the availability of permanent pacemakers has improved the prognosis for many people with cardiac arrhythmias.

Answer 3

That is a pretty slow heartbeat, but evidently you are still conscious. If you were passing out frequently then of course you would be very concerned. How long has it been since you have seen a doctor? You should see one if you see black when you rise suddenly from a chair.

I would exercise, like run up the stairs and down again and take the pulse again. It should then be more than 43 beats per minute. Like maybe 80 or 100. Is it just 43 first thing in the morning before you get out of bed? You might want to take it during the middle of the day or when you are moderately active.

Answer 4

Yes, definitley. Only well trained athletes have low hear rates, and I'm not sure if that low is even normal for them. You should be experienciing some fatigue with walking, or strenuous excerise. If you are taking meds, then something needs to be adjusted. It's important to have your doctor give you a thorough exam.asap! You can also experience dizziness, so don't delay getting a doctor's appt. Take Care!

Answer 5

Very, very few healthy, normal people will have a resting HR in the 40's (usually in a deep sleep). I work in an ICU and all of our patients are monitored so I see I wide range of heart rates but, this definitely falls out of "normal range" (60-100bpm). As previous posters have mentioned the cause could be a medication (this is the most frequent cause that I personally see). If you suspect it is medication related, do not stop your medication suddenly as this could cause severe side effects. Discuss this with your physician.

Answer 6

yes this is considerably low and should be evaluated quickly.

normal heartrate is a healthy adult is 60-80. some people (mostly athletes) run low naturally and some run high (like me-my norm is about 110).

if you're currently on medication for blood pressure-this could lower your heartrate. dehydration could lower it as well (it's the body's way of preserving energy and trying to keep itself alive)

make sure to have this checked out asap (24-48 hours max). it could be an indication of a serious problem.

Answer 7

Hi there,
I was interested in finding ways to naturally overcome hypothyroidism and I discovered this online resource called hypothyroidismrevolution. The author Tom Brimeyer explains an unconventional approach to hypothyroidism that I?ve never seen anywhere before. This is EYE-OPENING info for anyone who suffers from hypothyroidism and who really wants to learn the truth about how to permanently overcome hypothyroidism.

Answer 8

No, the more in shape you are, the slower your resting heart rate will be.

There are some athletes that have resting heart rates as slow as 16 Beats per minute.

Answer 9

The thyroid is a butterfly-shaped gland that sits low on the front of the neck. Your thyroid lies below your Adam’s apple, along the front of the windpipe. The thyroid has two side lobes, connected by a bridge (isthmus) in the middle. When the thyroid is its normal size, you’re unlikely to be able to feel it.
All types of hyperthyroidism are due to overproduction of thyroid hormones, but the condition can develop in several ways.
Thyroid hormone production can be suppressed or halted completely in these ways: https://tr.im/B4KYK

Answer 10

It depends! when you are resting for example sleeping a heart beat rate of 43per minute might not be too slow. but if it is while you are active it might be seen as low. the average is about 70per minute.
