Bradycardia or Low Heart Rate

Heart Rate Too Low

Bradycardia is when your heart rate is too slow.

Heart Rate Under 60 Beats Per Minute

Your heart normally beats from 60 to 100 times per minute in order to get enough oxygen-rich blood to the rest of your body. When your heart rate is under 60 beats per minute, you have bradycardia.

Signs and Symptoms Indicate Problem

Whether that is a problem depends on your age and physical condition. For example, people who are extremely physically fit may have slow heart rates. For them, a heart rate of fewer than 60 beats per minute may not pose any problem at all. But a serious disease or other condition can cause a bradycardia. Typically, bradycardia is a problem when you have signs and symptoms.

Complication

Complications can include:

• Fainting
  
• More dangerous arrhythmias
  
• Heart failure
