Specialized knowledge about irregularities and electrical problems needs to be available along with usual heart care facilities. It has been said that Chennai has electrophysiologists whose whole career has been dedicated to the study of rhythm problems. Among the most renowned electrophysiologists of Chennai is Dr. Deep Chandh Raja S, working at Kauvery Hospital and handling cases related to disorders of electrical circuits. The people who are detected to suffer from difficult ailments such as Atrial Fibrillation, Supraventricular tachycardia, and ectopic beats are being treated through innovative treatment methods. With the help of 3D cardiac mapping, Pulsed Field Ablation and Radiofrequency Ablation (RFA), heart rhythm specialists can treat the problem. They also implant devices like dual-chamber pacemakers, ICD, and CRT. In some risky groups of patients, they place special leadless pacemakers and Left Atrial Appendage (LAA) closure devices to control the chances of strokes without needing medication permanently. The specific diagnostic technique not only controls the arrhythmias but also stops dependence on medicines completely and restores normal heart rhythms.

An Implantable Cardioverter Defibrillator (ICD) is a small device placed under the skin to monitor heart rhythm and deliver an electrical shock if a life-threatening rhythm is detected. This device plays a crucial role in ICD treatment in Chennai by providing continuous heart monitoring and timely intervention to prevent sudden cardiac arrest.
