Pacemakers are effective treatments for a variety of bradyarrhythmias. Cardiac pacemakers generally consist of a pulse generator and one or more leads. The conventional temporary transvenous ventricular cardiac pacemaker utilizing a passive fixation lead is commonly associated with multiple complications such as increased infection rate, lead dislodgement, venous thrombosis, longer duration of hospital stay, and atrioventricular (AV) dyssynchrony. On the other hand, temporary permanent pacemakers (TPPM) utilize active fixation leads; hence, they provide lower capture thresholds, reliable pacing, lower rates of displacement, and fewer pacemaker-related infections. Here, we present a case of TPPM aiding AV synchrony restoration in complete heart block accompanying right ventricular (RV) infarction with refractory cardiogenic shock. Pacemakers are effective treatments for a variety of bradyarrhythmias. Cardiac pacemakers generally consist of a pulse generator and one or more leads. We present a case of TPPM aiding AV synchrony restoration in complete heart block accompanying RV infarction with refractory cardiogenic shock. TPPM pacing is a safe and effective technique for temporary bridge pacing to prevent AV dyssynchrony in hemodynamically unstable patients with cardiogenic shock from RV infarction and complete heart block. It also hastens recovery compared to a traditional single-chamber temporary pacemaker.
起搏器是治疗多种缓慢性心律失常的有效方法。心脏起搏器通常由脉冲发生器和一根或多根导线组成。使用被动固定导线的传统临时经静脉心室心脏起搏器通常会伴有多种并发症，如感染率增加、导线脱位、静脉血栓形成、住院时间延长以及房室（AV）不同步。另一方面，临时永久性起搏器（TPPM）使用主动固定导线；因此，它们具有较低的起搏阈值、可靠的起搏、较低的移位率以及较少的起搏器相关感染。在此，我们报告一例TPPM辅助恢复伴有右心室（RV）梗死和难治性心源性休克的完全性心脏传导阻滞患者的房室同步性。起搏器是治疗多种缓慢性心律失常的有效方法。心脏起搏器通常由脉冲发生器和一根或多根导线组成。我们报告一例TPPM辅助恢复伴有RV梗死和难治性心源性休克的完全性心脏传导阻滞患者的房室同步性。TPPM起搏是一种安全有效的临时桥接起搏技术，可防止因RV梗死和完全性心脏传导阻滞导致的心源性休克血流动力学不稳定患者发生房室不同步。与传统的单腔临时起搏器相比，它还能加速恢复。
