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.

A normal resting heart rate for a healthy adult is somewhere between 60 and 80 beats per minute, according to the American Heart Association. When heart rate habitually drops below 60 beats per minute, the condition is called bradycardia. Young adults or active athletes may have a slow heart rate without problems, but for many senior citizens, bradycardia is symptomatic of more serious conditions and may require the implantation of a pacemaker.
