What is Supraventricular Tachycardia? 10 Symptoms and Treatments

6. Treatment: Vagal Maneuvers

This common treatment for supraventricular tachycardia is considered a self-care treatment, but your doctor can teach you how to perform the procedures safely. If you experience a sudden episode of SVT, there are a plethora of vagal maneuvers that can help slow down your heart rate. For example, the diving reflex in which you immerse your face in ice-cold water will stimulate the vagus nerves. These particular nerves will slow down the electrical impulses that trigger the increase in heart rate. A carotid sinus massage involves putting pressure on your neck, but should only be done by a professional. The Valsalva maneuver is a breathing technique in which you forcefully breathing out, but with your mouth shut and your nose pinched closed. Simpler strategies include coughing or gagging.
