How Is Atrial Fibrillation Diagnosed?

Atrial Fibrillation is diagnosed through various tests, including:

  • Electrocardiogram (ECG or EKG): A test that records the heart’s electrical activity and can detect irregularities.
  • Holter Monitor: A portable ECG device worn for 24 to 48 hours to monitor heart activity over time.
  • Echocardiogram: An ultrasound of the heart that can assess its structure and function.
  • Blood Tests: To check for thyroid function and other potential causes of AFib.
  • Stress Test: To see how the heart performs under physical stress. Accurate diagnosis is essential for creating a treatment plan that suits the patient’s specific needs.
