Abstract
Transient pacemaker inhibition was observed in a patient with an external bipolar demand pulse generator. Recordings of the proximal, distal and bipolar electrograms showed extracardiac myopotentials only in the unipolar distal and bipolar configuration. These myopotentials which caused inhibition of the pulse generator were related to respiration and other maneuvers that resulted in active contraction of the diaphragm, thus proving their diaphragmatic origin.
摘要
在一名使用体外双极按需脉冲发生器的患者中观察到了短暂的起搏器抑制现象。近端、远端和双极心电图记录显示，仅在单极远端和双极配置中出现心外肌电位。这些导致脉冲发生器抑制的肌电位与呼吸及其他导致膈肌主动收缩的动作有关，从而证明了它们起源于膈肌。
