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.
What Is Bradycardia, or Slow Heartbeat? Bradycardia is a heartbeat of less than 60 beats per minute. In most healthy people, a normal heart rate is 60 to 100 beats per minute (BPM). Although a resting heart rate below 60 beats is considered bradycardia, it doesnât always signal a problem. What counts as an abnormally slow heartbeat for one person may not be the same for another. It can be affected by age and physical condition. Athletic adults can have a heart rate below 60 BPM, and that is normal for them. Your heart rate may fall below 60 BPM when you sleep but still be normal.
