Bradycardia

Need to know

• Symptoms of bradycardia icon plus

  Bradycardia may not cause symptoms, but if your heart rate is seriously low, your heart won't be able to pump oxygen-rich blood throughout your body effectively. If your brain or organs become oxygen-deprived, you may experience symptoms like:

  • fainting or blackouts (syncope)
  • chest pains
  • shortness of breath
  • weakness or fatigue
  • confusion or memory loss
  • tiring quickly or an inability to exert yourself

• Diagnosis icon plus

  Your GP or consultant will speak to you about your symptoms. If they suspect you have bradycardia, diagnostic tests may include:

  • an electrocardiogram (ECG) to measure the electrical activity of your heart
  • an echocardiogram to visualise the chambers of your heart
  • wearing a device called a Holter monitor to track your heart's rhythm over time

• Potential treatment options icon plus

  If you're diagnosed with an abnormally low heart rate, your treatment will depend on the cause and severity of your condition. Your consultant will work with you to determine the best treatment options and may suggest lifestyle changes to improve your condition. This may mean stopping or changing some medications or making certain lifestyle changes. If your bradycardia is related to an underlying condition, such as hypothyroidism or a congenital disease, your treatment will usually focus on managing that condition. In some cases, especially if the cause is an abnormality of the heart’s electrical system, you may need to have a pacemaker fitted.
