房室结双径路的电生理检查,以往采用静脉插管法进行心房调搏,此法设备昂贵,操作复杂,属创伤性。近年来,采用食道心房调搏技术进行房室结双径路等电生理检查,操作简单,无创易被患者接受。本文对70例受检查者检出的10例房室结双径路进行诊断条件、检查方法、房室结双径路和阵发性室上性心动过速(PSVT)电生理机制等初步探讨。
Atrioventricular node dual-path electrophysiological examination, past the use of venous intubation atrial pacing, this method is expensive equipment, complex operation, is a traumatic. In recent years, the use of esophageal atrial pacing technology for atrioventricular nodal pathways and other electrophysiological examination, simple operation, non-invasive and easy to be accepted by patients. In this paper, 70 cases of subjects detected by the detection of 10 cases of atrioventricular junction dual pathways diagnostic conditions, examination methods, atrioventricular node dual pathways and paroxysmal supraventricular tachycardia (PSVT) electrophysiological mechanism of preliminary study.
