Bradycardia in an adult is any heart rate less than 60 beats per minute (BPM), although symptoms usually manifest only for heart rates less than 50. The word bradycardia is from the Greek Î²ÏÎ±Î´ÏÏ, bradys slow, and ÎºÎ±ÏÎ´Î¯Î±, kardia, heart.
While this constitutes sinus bradycardia, it is a âphysiologicâ form of sinus bradycardia â which means the heart rate is appropriate to the bodyâs needs, and thus, the sinus bradycardia is normal. Sinus bradycardia is considered a problem if the heart rate is too slow to meet the bodyâs needs.
