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.
Treatment also depends on the symptoms. If bradycardia doesn't cause symptoms, it usually isn't treated. If damage to the heart's electrical system causes your heart to beat too slowly, you will probably need to have a pacemaker. A pacemaker is a device placed under your skin that helps correct the slow heart rate. People older than 65 are most likely to have a type of bradycardia that requires a pacemaker.
