From: A successful case of left bundle branch area pacing using stylet-driven pacing leads with a steerable delivery sheath in patients with structural heart disease

Fig. 3

Typical ‘r’ pattern in lead V1, a peak left ventricular activation time (LVAT) of 59 ms in lead V5, V6–V1 interval of 58 ms, and a QRS duration of 128 ms. The paced LVAT duration measured in lead V6 was short and constant at differential pacing output (5 V → 1 V) and a discrete local ventricular electrogram (arrow) is seen for the pacing lead at low pacing output
