Summary– Pacemakers are lifesaving devices that are being implanted with various indications, such as sinus node disease, atrioventricular block, and cardiac resynchronization therapy. Impedance measurement is one of the integral tests by which electrical resistance in pacing lead is tested. In this paper, we report an interesting observation of sudden impedance rise after ventricular tachycardia ablation with transmural lesions, which subsequently normalized without any need for intervention. The clinical implication of our findings is that careful observation might be indicated instead of lead replacement in case of a sudden surge in epicardial lead impedance after endocardial ablation owing that the impedance surge might be reversible.
