Tachycardia, supraventricular is an irregularly fast or unpredictable heartbeat (arrhythmia) that involves the upper chambers of the heart. Between 60 and 100 per minute, the normal heartbeats. A heart rate of over 100 beats per minute is known to as tachycardia. The heart beats 150 to 220 times per minute during an event of SVT, but it can rarely beat quickly or slowly.

Most patients don’t require any activity limitations or treatment. Others may require lifestyle modifications, medication, or heart operations to reduce or eradicate their rapid heartbeats and symptoms.


  • Atrioventricular reciprocating tachycardia (AVRT)
  • Atrioventricular nodal reentrant tachycardia (AVNRT)
  • Atrial tachycardia

Tachycardia, supraventricular can also be classified as:

  • Multifocal atrial tachycardia 
  • Sinus tachycardia
  • Inappropriate sinus tachycardia
  • Nonparoxysmal junctional tachycardia
  • Sinus nodal reentrant tachycardia 
  • Junctional ectopic tachycardia 


The major sign of tachycardia, supraventricular is a rapid heartbeat (100 beats per minute or more) that can persist anywhere from a few minutes to several days. The rapid heartbeat may come and go unexpectedly, with periods of normal heart rates in between.

Tachycardia, supraventricular can cause the following signs:

  • Chest pain
  • Fast heartbeat
  • Hammering or fluttering in the chest
  • Breathing problems
  • Sweating
  • Fatigue
  • Fainting
  • Dizziness 

The clinical manifestations of supraventricular, tachycardia in newborns and young children might be difficult to recognize. Sweating, poor nutrition, pale skin, and a quick heartbeat are among them.


Your health care practitioner will evaluate you and ask any questions about your signs and health history to diagnose tachycardia, supraventricular. Blood tests are routinely done to rule out illnesses like thyroid disease, which can cause similar signs.

The following tests can be used to assess:

  • Holter monitor
  • ECG
  • Echocardiogram
  • Event recorder
  • Implantable loop recorder

Other tests that could be conducted include:

  • Tilt table test
  • Exercise stress test
  • Electrophysiological


The vast majority of patients with tachycardia, supraventricular do not require treatment. If you experience long or frequent episodes, your doctor might suggest the following:

  • Vagal maneuvers
  • Carotid sinus massage
  • Cardioversion
  • Medications
  • Catheter ablation
  • Pacemaker
