Atrial pacing and right ventricular (RV) pacing are both associated with adverse outcomes among patients with first‐degree atrioventricular block (1°AVB). His‐bundle pacing (HBP) provides physiological activation of the ventricle and may be able to improve both atrioventricular (AV) and inter‐ventricular synchrony in 1°AVB patients. This study evaluates the acute echocardiographic and hemodynamic effects of atrial, atrial‐His‐bundle sequential (AH), and atrial‐ventricular (AV) sequential pacing in 1°AVB patients.
