Detailed explanation-1: -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.

Detailed explanation-2: -What is bradycardia? Bradycardia is a type of abnormal heart rhythm, or arrhythmia. It occurs when the heart beats very slowly-less than 60 beats per minute. A normal heartbeat begins with an electrical impulse from the sinus node, a small area in the heart’s right atrium (right upper chamber).

Detailed explanation-3: -The word “bradycardia” is from the Greek bradys “slow", and kardia “heart".

Detailed explanation-4: -Bradycardia is a heart rate that’s too slow. What’s considered too slow can depend on your age and physical condition. Elderly people, for example, are more prone to bradycardia. In general, for adults, a resting heart rate of fewer than 60 beats per minute (BPM) qualifies as bradycardia.

Detailed explanation-5: -Both terms mean having a slower than average heart rate. Bradycardia describes a resting heart rate below 60 beats per minute. Bradyarrhythmia describes a slow heart rate caused by an irregular heartbeat (arrhythmia).
