Comprehensive electrophysiologic evaluation with insertion and repositioning of multiple electrode catheters, induction or attempted induction of an arrhythmia with right atrial pacing and recording and catheter ablation of arrhythmogenic focus, including intracardiac electrophysiologic 3-dimensional mapping, right ventricular pacing and recording, left atrial pacing and recording from coronary sinus or left atrium, and His bundle recording, when performed; with treatment of ventricular tachycardia or focus of ventricular ectopy including left ventricular pacing and recording, when performed

A comprehensive electrophysiologic evaluation (EPS) is a specialized procedure designed to assess and treat abnormal heart rhythms, known as arrhythmias. This procedure involves the insertion and repositioning of multiple electrode catheters, which are thin, flexible tubes equipped with electrodes that can both record electrical activity and deliver electrical impulses to the heart. The primary goal of the EPS is to induce or attempt to induce an arrhythmia through right atrial pacing and recording, allowing healthcare professionals to study the heart's electrical conduction system in detail. This evaluation is crucial for identifying the specific arrhythmogenic focus, or the area of the heart responsible for the abnormal rhythm. During the procedure, intracardiac electrophysiologic 3-dimensional mapping may be utilized, which involves creating a detailed computer-generated model of the heart's electrical activity. This mapping helps in pinpointing the exact location of the arrhythmia. The procedure may also include right ventricular pacing and recording, as well as left atrial pacing and recording from the coronary sinus or left atrium, and potentially His bundle recording, which provides additional insights into the heart's conduction pathways. Once the arrhythmogenic focus is identified, catheter ablation is performed. This involves applying energy—such as radiofrequency, microwave, or cryoablation—to destroy the tissue causing the arrhythmia, thereby interrupting the abnormal electrical signals. The procedure is comprehensive, as it not only aims to treat life-threatening ventricular tachycardia or a focus of ventricular ectopy but also ensures that the arrhythmia cannot be induced again after the ablation. This thorough approach is essential for effective management of patients with significant arrhythmias, enhancing their safety and quality of life.
