Why the study?
To assess differences in blood flow momentum and kinetic energy dissipation in a model of cardiac dyssynchrony induced by electrical right ventricular apical stimulation compared with spontaneous sinus rhythm.
Does right ventricular apical pacing alter blood flow momentum and kinetic energy dissipation compared to sinus rhythm in patients with preserved ejection fraction?
Does right ventricular apical pacing alter blood flow momentum and kinetic energy dissipation compared to sinus rhythm in patients with preserved ejection fraction?
Right ventricular apical pacing induces adverse intraventricular flow patterns and kinetic energy dissipation that are associated with deterioration of left ventricular global longitudinal strain.

RVA pacing may disrupt LV flow efficiency in preserved EF; leaves open links to clinical outcomes.
