Diagnosis Your doctor will review your symptoms and your medical history and conduct a physical examination first. Heart-monitoring tests specific to arrhythmia may be performed:
  • Electrocardiogram (ECG) to measure the timing and duration of each electrical phase in your heartbeat.
  • Holter monitor to record your heart's activity as you go about your routine.
  • Event monitor to check your heart rhythm at the time of your symptoms.
  • Echocardiogram to produce images of your heart's size, structure and motion.
  • Implantable loop recorder to detect abnormal heart rhythms.
If an arrhythmia is not found, tests that may conduct include:
  • Stress test.
  • Tilt table test.
  • Electrophysiological testing and mapping.
Treatment Most people with supraventricular tachycardia do not require medical treatment. If your situation is prolonged or frequent, the following may be recommended:
  • Carotid sinus massage to release certain chemicals that slow the heart rate.
  • Vagal maneuvers which affect the nervous system that controls your heartbeat (vagus nerves), often causing your heart rate to slow.
  • Cardioversion in which a shock current affects the electrical impulses in your heart and can restore a normal rhythm.
  • Medications to control your heart rate or restore a normal heart rhythm.
  • Catheter ablation to damage (ablate) a small spot of heart tissue and create an electrical block along the pathway that's causing your arrhythmia.
  • Pacemaker (rare) to emit electrical impulses that stimulate your heart to beat at a normal rate.
