what are the dangers of a low pulse rate?

If bradycardia causes symptoms, possible complications can include: Frequent fainting spells. Inability of the heart to pump enough blood (heart failure) Sudden cardiac arrest or sudden death.

You should visit your doctor if your heart rate is consistently above 100 beats per minute or below 60 beats per minute (and you're not an athlete). In addition to a heart rate, you should look out for other symptoms such as: being short of breath.

Your low resting heart rate indicates that you have a big bucket. The fact that your stroke volume is relatively high, and your maximum heart rate is over 200bpm is a good thing, because it means that you have a large cardiac output (flow of blood in litres per minute = heart rate x stroke volume).

Heart rate is a good measure of how far a person is pushing themselves during exercise. A low heart rate during exercise may mean that a person could increase the intensity of that activity, while a heart rate that is too high can be dangerous.

For some people, a slow heart rate does not cause any problems. It can be a sign of being very fit. Healthy young adults and athletes often have heart rates of less than 60 beats a minute. In other people, bradycardia is a sign of a problem with the heart's electrical system.

Having bradycardia (say "bray-dee-KAR-dee-uh") means that your heart beats very slowly. For most people, a heart rate of 60 to 100 beats a minute while at rest is considered normal. If your heart beats less than 60 times a minute, it is slower than normal.

Generally speaking, the literature on this issue shows that heart rate greater than 80 beats per minute significantly increases the risk of cardiovascular complications, morbidity and mortality, and that heart rate greater than 80-85 beats per minute can be considered as a threshold for tachycardia [29].

The rapid heartbeats, caused by changes in the electrical system of your heart, may lead to fainting, and can be life-threatening. In some cases, your heart's rhythm may be so erratic that it can cause sudden death. You can be born with a genetic mutation that puts you at risk of long QT syndrome.

Healthy young adults and athletes often have heart rates of less than 60 beats a minute. In other people, bradycardia is a sign of a problem with the heart's electrical system. It means that the heart's natural pacemaker isn't working right or that the electrical pathways of the heart are disrupted.

When the heart's electrical circuits aren't properly functioning, the result can be a high heart rate coupled with low blood pressure, Dr. Taigen explains. “When the heart has a fast, abnormal rhythm — anything over 100, but closer to 160 beats per minute — it can't adequately fill with blood.

But there are exceptions. Your heart rate may fall below 60 BPM during deep sleep. And physically active adults (and athletes) often have a resting heart rate slower than 60 BPM.

Heart problems: Among the heart conditions that can lead to low blood pressure are an abnormally low heart rate (bradycardia), problems with heart valves, heart attack and heart failure. Your heart may not be able to circulate enough blood to meet your body's needs.

Some heart conditions that can lead to low blood pressure include extremely low heart rate (bradycardia), heart valve problems, heart attack and heart failure. Endocrine problems.
