This is a type of abnormal heart rhythm caused by a specific abnormal electrical circuit in the heart. This also results in a rapid heart rate (tachycardia) and can be treated with medication, cardioversion (if an emergency) or procedures such as ablation. This extra electrical pathway in the heart, allows electrical impulses to travel in a circular loop, resulting in a rapid heart rate. This condition is usually benign but can cause symptoms such as palpitations, dizziness and shortness of breath. If left untreated, it can occasionally lead to more serious problems such as heart failure or stroke. The management of AVRT typically involves a combination of medical therapy and invasive procedures. Medical therapy options include: Vagal manoeuvres, such as bearing down or coughing, can sometimes interrupt the abnormal electrical pathway and stop the tachycardia. Invasive procedures include: Radiofrequency ablation: A procedure in which a catheter is inserted into the heart and used to destroy the abnormal electrical pathway. Cardioversion: A procedure in which an electric shock is delivered to the heart to restore a normal rhythm. The choice of treatment will depend on various factors, including the patient’s symptoms, underlying health conditions, and the underlying cause of the tachycardia. It is important to work closely with a cardiologist to determine the best course of treatment.
