Complete occlusion of the sinoatrial node artery can be a complication of percutaneous intervention (PCI) to the right coronary artery (RCA). When this happens, dysfunction of the sinus node may follow resulting in sinus arrest. When this occurs, it is usually transient and as such, is typically not accompanied by hemodynamic instability. Permanent sinus arrest and shock state may, however, occur on rare occasions. The presence of junctional rhythms on the electrocardiogram (ECG) may predict the occurrence of these permanent arrhythmias and cardiogenic shock. In this case report, we present a 78-year-old woman who developed cardiogenic shock secondary to sinus arrest following PCI to RCA. Her ECG showed junctional rhythm, and she went on to require permanent ventricular pacing. This illustrates a known but rare complication of PCI to RCA.
右冠状动脉（RCA）经皮介入治疗（PCI）后可发生窦房结动脉完全闭塞。此时，窦房结功能可能受到影响，导致窦性停搏。这种情况通常是短暂的，因此通常不会伴有血流动力学不稳定。然而，在极少数情况下可能会发生永久性窦性停搏和休克状态。心电图（ECG）上出现交界性节律可能预示着这些永久性心律失常和心源性休克的发生。在本病例报告中，我们介绍了一位 78 岁女性，她在接受 RCA 的 PCI 后发生窦房结停搏导致心源性休克。她的心电图显示交界性节律，随后需要永久性心室起搏。这说明了 RCA 的 PCI 已知但罕见的并发症。
