False triggering with a ventricular triggered pacemaker and false inhibition with a ventricular inhibited pacemaker were observed in two patients with complete heart block. These arrhythmias were considered to be attributable to false sensing with a demand pacemaker. Both in vitro and in vivo studies were performed to elucidate the mechanism of these false sensings, and the false sensings were reproduced in a series of experiments. Loose contact of the tip of electrodes to myocardial tissue, refractory period, the distance between two electrodes, and the after potential and its dv/dt of pacemaker impulses are considered to affect the performance of demand pacers.
在两名完全性心脏传导阻滞患者中观察到心室触发型起搏器的误触发以及心室抑制型起搏器的误抑制。这些心律失常被认为是按需起搏器误感知所致。进行了体外和体内研究以阐明这些误感知的机制，并且在一系列实验中重现了误感知。电极尖端与心肌组织的松散接触、不应期、两个电极之间的距离以及起搏器脉冲的后电位及其dv/dt被认为会影响按需起搏器的性能。
