Po-703-07 improved left ventricular ejection fraction and stroke volume with his bundle pacing are associated with higher magnitudes of global longitudinal and circumferential strains

In recently reported clinical studies, His bundle pacing (HBP) improved cardiac function in patients with pre-existing heart failure. The effect of HBP vs RBP on global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) in the absence of pre-existing heart failure has not yet been explored.
