We report a case of ventricular fibrillation in the first episode and ventricular tachycardia in the second episode that occurred with use of electrosurgical unit during redo MVR procedure. Both arrhythmia occurred five to ten seconds after application of the electrosurgical knife in the coagulation mode to the sternal periosteum. The patient was immediately resuscitated with return to sinus rhythm using direct-current electroshock. In the literature, it was reported that large direct-current potentials were generated during electrosurgery and that these potentials increased with increasing sparking at the active electrode. Care should be always taken because they may cause fatal ventricular arrhythmia.
我们报告一例在再次二尖瓣置换术（redo MVR）过程中使用电外科设备时首次发生心室颤动、第二次发生室性心动过速的病例。两种心律失常均在以凝血模式将电外科刀应用于胸骨骨膜后五到十秒出现。患者立即通过直流电击复苏并恢复窦性心律。文献报道，电外科手术期间会产生大量直流电位，且这些电位会随着有源电极处火花的增加而升高。应始终小心，因为它们可能导致致命的室性心律失常。
