Treatment Options for Supraventricular Tachycardia

Supraventricular tachycardia, often referred to as paroxysmal supraventricular tachycardia (PSVT), is generally not life-threatening and has a favorable prognosis. Patients often experience symptoms related to increased vagal tone, which can sometimes be managed with simple, non-invasive techniques. One such method involves using a tongue depressor to stimulate the back of the throat, triggering a gag reflex that helps interrupt the abnormal heart rhythm. This technique can effectively reduce vagal stimulation and restore normal heart rate.

Physical Maneuvers for Managing SVT

Another commonly used approach is applying gentle pressure to the carotid sinus, located in the neck. This maneuver, known as carotid sinus massage, can also help stop the episode by influencing the vagus nerve and slowing down the heart rate. These physical techniques are usually the first line of treatment and are especially useful for managing sudden episodes of SVT.

Medical Interventions for Persistent Cases

Medication and Cardioversion

If these initial methods fail to restore normal heart rhythm, medications such as beta-blockers or calcium channel blockers may be prescribed to slow the heart rate. In more urgent situations, healthcare providers may use electrical cardioversion to reset the heart's rhythm. This procedure delivers a controlled electric shock to the heart, restoring a normal heartbeat in cases where medications or physical maneuvers have not worked.

Long-Term Treatment with Catheter Ablation

For individuals who experience frequent or severe episodes, a more permanent solution like radiofrequency catheter ablation may be recommended. This minimally invasive procedure targets and destroys the abnormal electrical pathways in the heart that cause SVT, offering long-term relief and significantly reducing the risk of future episodes.

Understanding the Symptoms and Outlook

Paroxysmal supraventricular tachycardia typically starts and stops suddenly, often leaving patients feeling uneasy during an episode. Common symptoms include palpitations, shortness of breath, chest discomfort, and anxiety. However, once the episode subsides, many patients report feeling completely back to normal. With proper management and treatment, the overall prognosis for SVT is excellent, and most patients can lead active, healthy lives.
