Left bundle branch area pacing in patients with baseline narrow, left, or right bundle branch block QRS patterns: insights into electrocardiographic and echocardiographic features

Does left bundle branch area pacing improve or preserve intra-ventricular mechanical synchrony in patients with narrow, LBBB, or RBBB QRS patterns?

Left bundle branch area pacing preserves mechanical synchrony in patients with narrow or RBBB QRS patterns and improves synchrony in those with LBBB.
