Bradycardia

Symptoms

A slower than normal heartbeat (bradycardia) can prevent the brain and other organs from getting enough oxygen, possibly causing these signs and symptoms:

  • Chest pain
  • Confusion or memory problems
  • Dizziness or lightheadedness
  • Easily tiring during physical activity
  • Fatigue
  • Fainting (syncope) or near-fainting
  • Shortness of breath

When to see a doctor

Many things can cause signs and symptoms of bradycardia. It's important to get a prompt, accurate diagnosis and appropriate care. See your health care provider if you or your child has symptoms of bradycardia.

If you faint, have difficulty breathing or have chest pain lasting more than a few minutes, call 911 or emergency medical services. Seek emergency care for anyone with these symptoms.
