VF Attack in a Patient with High-grade Atrioventricular Block and QT Prolongation During Implantation of Myocardial Electrode: A Case Report

Abstract

  A 53-year-old female patient underwent implantation of myocardial electrode for high-grade atrioventricular block under general anesthesia. When an operator ablated fat on the pericardium, ventricular fibrillation suddenly occurred. Immediate electrical defibrillation following cardiac massage restored the patient's heartbeat successfully. Then we inserted a temporary transvenous pacing wire. After induction of electronic pacing to avoid fatal arrhythmia, the operation was performed uneventfully. The present case suggests that it is necessary to insert a temporary pacing wire before surgery in cases with high-grade atrioventricular block.
