case_images: The preoperative electrocardiogram (ECG) showed sinus rhythm with a narrow QRS complex (Figure 1(a)). At the time of TAVI, the patient developed LBBB (average QRS duration of 180 ms) with a prolonged PR interval of 240 ms (Figure 1(b)). The paced QRS duration on 12 lead ECG was 125 ms consistent with nonselective HBP (para-Hisian morphology) (Figure 1(c)).
