Core Tip

Core Tip: We present a case who received cardiac pacing through the coronary sinus and provide a summary of evidence in the current literature. A 55-year-old woman with unstable bradycardia complicating cardiogenic shock achieved cardiac resynchronization with placement of a temporary pacing wire to the coronary sinus. This modality, compared to pacing through the right ventricle apex, may induce a more physiologic ventricular depolarization and decrease ventricular dyssynchrony. This approach was safely applied in patients who had risks of ventricular dyssynchrony or required temporary atrial pacing. Pitfalls such as technical requirements and potential complications should be considered prior to electrode lead placement.
