Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). [1] While bradycardia can result from various pathologic processes, it is commonly a physiologic response to cardiovascular conditioning or due to asymptomatic type 1 atrioventricular block .
Example ultrasound of an athlete. Athlete's heart most often does not have any physical symptoms, although an indicator would be a consistently low resting heart rate.. Athletes with AHS often do not realize they have the condition unless they undergo specific medical tests, because athlete's heart is a normal, physiological adaptation of the body to the stresses of physical conditioning and ...

Bradycardia, on the other hand, occurs when your heart rate falls below 60 bpm. Conditions including obstructive sleep apnea and chemical imbalances in the blood can cause bradycardia.
Trained athletes tend to have slow resting heart rates, and resting bradycardia in athletes should not be considered abnormal if the individual has no symptoms associated with it. For example, Miguel Indurain , a Spanish cyclist and five time Tour de France winner, had a resting heart rate of 28 beats per minute, [ 68 ] one of the lowest ever ...
A few short bursts of exercise throughout the day may reduce heart disease risk by 50%, according to new research. Women specifically showed the most pronounced effects of short bursts of activity ...
Sinus bradycardia is a sinus rhythm with a reduced rate of electrical discharge from the sinoatrial node, resulting in a bradycardia, a heart rate that is lower than the normal range (60–100 beats per minute for adult humans).
Reflex bradycardia is a bradycardia (decrease in heart rate) in response to the baroreceptor reflex, one of the body's homeostatic mechanisms for preventing abnormal increases in blood pressure. In the presence of high mean arterial pressure , the baroreceptor reflex produces a reflex bradycardia as a method of decreasing blood pressure by ...
