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.

Types and Symptoms

TYPES

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

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

Other tests that could be conducted include:

  • Tilt table test
  • Exercise stress test
  • Electrophysiological

TREATMENT

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
