Your doctor will review your symptoms and your medical history and conduct a physical examination
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.
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.
