How is it treated?

Treatments for tachycardia are designed to address not only the root cause of tachycardia, but also to prevent tachycardia in the future. Your specialist from Medanta might recommend various modes of treatment including:

..

  • Vagal maneuvers

    Vagal maneuvers have an impact on the vagus nerve that regulates the heartbeat. The maneuvers include actions like coughing, bearing down as if you're having a bowel movement and putting an ice pack on your face.

  • Medication

    Treatment through medications involves the injection of an anti-arrhythmic medication to restore a normal heart rate. The doctor may administer a pill version of an anti-arrhythmic drug if you vagal maneuvers aren't effective.

  • Cardioversion

    In this procedure, a shock is delivered to the heart through paddles, an automated external defibrillator (AED) or patches on the chest. The shocks help in restoring a normal rhythm.
