ABSTRACT BACKGROUND: Temporary transvenous pacing through the coronary sinus is a novel approach rarely used in treating unstable bradycardia. This modality could provide cardiac pacing while achieving better ventricular synchrony. We present a case who received cardiac pacing through the coronary sinus and provide a summary of evidence in the current literature. CASE SUMMARY: A 55-year-old woman with a history of advanced heart failure was admitted to the rehabilitation ward after a recent stroke. During hospitalization, she had paroxysmal atrial fibrillation with rapid ventricular response resulting from fluid overload. While atrial fibrillation was spontaneously reversed to sinus rhythm after diuresis, she developed multiple episodes of polymorphic ventricular tachycardia along with sinus bradycardia and prolonged QTc interval. She became hypotens ive despite appropriate medical management. Pacing through her implantable cardioverter-defibrillator was attempted but worsened her hypotension. Ventricular dyssynchrony was suspected. Temporary transvenous atrial pacing through the coronary sinus was performed, which stabilized her blood pressure and improved end-organ perfusion. A permanent biventricular pacemaker was later implanted, and she was safely discharged to a nursing home. CONCLUSION: Temporary transvenous pacing through the coronary sinus, a novel approach to treat unstable bradycardia, may reduce ventricular dyssynchrony.
