What is Bradycardia?

A heart rate of less than 60 beats per minute (BPM) in adults is called bradycardia. What's too slow for you may depend on your age and physical condition.

  • Physically active adults (and athletes) often have a resting heart rate slower than 60 BPM but it doesn't cause problems and is normal for them.
  • Your heart rate may fall below 60 BPM during deep sleep.
  • Elderly people are more prone to problems with a slow heart rate.

Causes of bradycardia

  • Problems with the sinoatrial (SA) node, sometimes called the heart's natural pacemaker
  • Problems in the conduction pathways of the heart
  • Metabolic problems such as hypothyroidism
  • Damage to the heart from heart attack or heart disease
