Abnormal Heart Rhythm / Arrhythmia

Abnormal Heart Rhythm / Arrhythmia - Diagnosis

An abnormal heart rhythm or arrhythmia is diagnosed by a physical examination, electrocardiograms and electrophysiologic studies. However, as arrhythmias are not always present, they may not occur during the physical examination.

You may have already received diagnostic tests to confirm if you have an arrhythmia and its likely causes. Otherwise, your doctor may discuss some of these tests with you to see if you have AF:

  • Electrocardiogram (ECG)
  • Holter (continuous heart rhythm monitoring between 24 to 48 hours)
  • Blood tests and ultrasound of the heart may be required
