Complications during electrophysiological procedures, such as electrophysiological studies or ablations, although relatively rare, may occur. Some potential complications during electrophysiological procedures that one may encounter include arrhythmias, pericardial effusion, cardiac tamponade or perforation, vascular damage, neurologic complications, injection site bleeding, phrenic nerve palsy, myocardial infarction, and anesthesia-related complications. Early recognition of these complications and rapid response are key to their proper management and ensuring patient safety. Any complication during electrophysiological procedures requires an individualized approach. Medical staff and physicians are trained to recognize and treat acute complications to ensure patient safety and well-being. It is important to remain calm and work with the team of professionals to achieve the best possible outcomes for the patient. (1-3)
