摘要
报道应用经食管心室调傅方法,终止经药物治疗无效的顽固性阵发性室性心动过速7例。食管电极导管插入40—46cm,平均44.3cm,刺激脉冲的脉宽为10ms,采用短阵超速、亚速或程控心室刺激均获成功。认为在顽固性阵发性室性心动过速的紧急处理中,经食管心室调搏亦是一种有效的急救措施。
Seven patients with refractory paroxysmal ventricular tachycardiafailed to antiarrhythmic drug were successfully treated by transesophagealventricular pacing(TEVP). A hexapolar electrode catheter was inserted through the nostril intothe patient′s esophagus for 40--46cm. The pulse stimuli were delivered viathe electrode catheter with a multifunction programmable cardiac stimulator.The output power was 35--45 voltages, the pulse duration was 10 milliseconds.PVT in all patients was terminated by burst stimuli, underdrive stimuli orprogrammed ventr(?)ular extrastimulation. No complication was foundduring this process.We believed that TEVP is an effective method foremergency management of refractory paroxysmal ventricular tachycardia,
