临床上,可经食道通过各种形式的阈上程控电刺激终止阵发性室上性心动过速(PSVT),但这些阈上刺激方法有可能引发心房颤动,且刺激电压较高,可给病人带来痛苦。因此,寻找一种经食道、低电压、安全的终止PSVT的方法,具有重大的临床意义。最近,我们探讨了一种终止PSVT的阈下电刺激(STS)方法,经治2例取得较好的效果,报告如下。 对象与方法 2例均为男性,年龄分别为23、38 Clinically, paroxysmal supraventricular tachycardia (PSVT) can be terminated by various forms of suprathreshold electrical stimulation via the esophagus, but these supra-threshold stimulation methods may trigger atrial fibrillation and stimulate a higher voltage Patient brings pain. Therefore, to find a transesophageal, low voltage, safe termination of PSVT method has great clinical significance. Recently, we explored a termination of PSVT subthreshold electrostimulation (STS) method, achieved good results in 2 cases, the report is as follows. Subjects and methods were 2 cases of men, the ages were 23,38
