Why the study?
Does positioning the atrial electrode on the atrial septum compared to the right atrial appendage alter hemodynamics during AV sequential pacing in patients without heart failure?

No stroke volume difference with septal versus appendage pacing in non-HF patients; leaves open site selection effects in HF.
Does positioning the atrial electrode on the atrial septum compared to the right atrial appendage alter hemodynamics during AV sequential pacing in patients without heart failure?
Altering the left AV interval by changing the atrial pacing site from the right atrial appendage to the atrial septum has minimal hemodynamic effect on stroke volume in patients without heart failure.
