快速型心律失常是临床常见的一种危重症,若不及时治疗或治疗无效者,可诱发心力衰竭、心源性休克、心室颤动以至于心跳骤停。近年来,快速型心律失常疗法的重要进展是采用外科手术治疗。目前,WPW 综合征伴发的快速型心律失常的手术疗效大于90%,室性心动过速的疗效亦达50～80%。但取得手术成功的关键有赖于术前和术时对病人进行的临床电生理检查。 Rapid arrhythmia is a common clinical critically ill, if not treated or treated ineffective, can induce heart failure, cardiogenic shock, ventricular fibrillation and cardiac arrest. In recent years, an important advance in tachyarrhythmia therapies has been surgical treatment. Currently, WPW syndrome with tachyarrhythmia surgery effect of more than 90%, the efficacy of ventricular tachycardia also reached 50 to 80%. But the key to successful surgery relies on the clinical electrophysiological examination of the patient before and during surgery.
