What tests are used to diagnose tachycardia?

ANSWER

These may include:

  • Electrocardiogram (ECG or EKG). This records the electrical activity in your heart and helps your doctor search for things that don’t look normal. You may have to wear a holter monitor, a portable machine that records your ECG signals over 24 hours.
  • Exercise stress test. Your doctor will have you walk on a treadmill while he monitors your heart activity.
  • Magnetic source imaging: This measures the heart muscle’s magnetic fields and looks for weaknesses.
