Bradycardia (brad-e-KAHR-dee-uh) is a slow heart rate. The hearts of adults at rest usually beat between 60 and 100 times a minute. If you have bradycardia, your heart beats fewer than 60 times a minute. Bradycardia can be a serious problem if the heart rate is very slow and the heart can't pump enough oxygen-rich blood to the body.
Diagnosis. To diagnose bradycardia, a health care provider will usually perform a physical exam and listen to your heart with a stethoscope. He or she may ask you questions about your symptoms and medical history. Your health care provider may recommend tests to check your heart rate and see if you have a heart problem that can cause bradycardia.
A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute. To measure your heart rate, simply check your pulse.
In a healthy person, low resting heart rate means that the periferic tissues are more efficient at using oxygen. Edit: that is why athletes have low RHR, their training makes them use oxygen very efficiently, and when they're not exercicing (resting), the body goes "whoop, that is more than enough oxygen".
In a healthy heart, this signaling process usually goes smoothly. The resting heart rate is typically 60 to 100 beats a minute. But in tachycardia, something causes the heart to beat faster than 100 beats a minute. Risk factors. In general, things that may raise the risk of irregular heart rhythms that commonly cause tachycardia include ...
But a low resting heart rate doesn't always mean there's a problem. If you're physically fit, your heart may be able to pump enough blood to the body with less than 60 beats a minute. If you have a slow heart rate and your heart isn't pumping enough blood, you may have a type of bradycardia. Types of bradycardias include: Sick sinus syndrome.
Lightheadedness or dizziness. Shortness of breath. Sweating. Weakness or extreme tiredness. Nausea. Some people with atrial tachycardia do not notice symptoms. Atrial tachycardia symptoms may be hard to see in infants and young children. Symptoms of atrial tachycardia in children can include: Poor feeding.
Low blood pressure is common in the first 24 weeks of pregnancy. After a person gives birth, blood pressure usually returns to the level that it was before pregnancy. Heart and heart valve conditions. A heart attack, heart failure, heart valve disease and a slow heart rate called bradycardia can cause low blood pressure.
To everyone posting- if you have a low resting heart rate, please wear a RunID that says you’re resting heart rate is low. If you ever have a medical emergency, first responders would be very concerned and may take action if they see your heart rate drop to, say, 45. This should almost be a public service announcement.
Resting heart rate is in general a way to see how healthy and fit you are. The lower it is, if there is no heart condition, the better. Very active people normally have resting heart rate between 40-60, professional athletes sometimes 30-40, normal people 60-80. Everything above 100 is way too high.
