An unusual type of exist block from a transvenous pacing electrode was recorded in a 63-year-old man with an acute inferior infarct and cardiogenic shock. The pacemaker artefact to QRS interval increased gradually till there was loss of capture. A gradual change from I:I pacing rhythm to 4:3 and 3:2 Wenckebach cycles was recorded. This was followed by a fixed 2:I pacemaker artefact to QRS block.
在一名患有急性下壁心肌梗死并伴有心源性休克的63岁男性患者中，记录到了经静脉起搏电极出现的一种不寻常的存在阻滞情况。起搏器伪迹至QRS波间期逐渐延长，直至出现夺获丧失。记录到起搏节律从1:1逐渐转变为4:3和3:2文氏周期。随后出现了固定的2:1起搏器伪迹至QRS波阻滞。
