What is the range for bradycardia?

Answer 1

Bradycardia (range 49–60 beats/minute) requiring medical intervention.

Answer 2

Bradycardia, as applied to adult medicine, is defined as a resting heart rate of under 60 beats per minute, though it is seldom symptomatic until the rate drops below 50 beat/min. 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.

The term relative bradycardia is used to explain a heart rate that, while not technically below 60 beats per minute, is considered too slow for the individual's current medical condition.

Answer 3

Properly termed Sinus bradycardia: it is a regular but unusually slow heart beat (60 beats/minute or less at rest). Sinus bradycardia can be the result of many things including good physical fitness, medications, and some forms of heart block. "Sinus" refers to the sinus node, the heart's natural pacemaker which creates the normal regular heartbeat. "Bradycardia" means that the heart rate is slower than normal. Fainting can occur with sinus bradycardia if the heart slows down even more. This can occur, for example, when the vagus nerve sends a signal to the heart that suddenly drops the heart rate. Choking or gagging can trigger this response which is called the vasovagal reflex. (For interest, US President George W. Bush has sinus bradycardia and had an episode of fainting due to a vasovagal response after choking on a pretzel.)
