Abstract
-Experiments were carried out to determine the influence of ventricular pacing and ventricular-coupled pacing on the relation between left ventricular end-diastolic pressure and circumference or segment length. Compared to atrial pacing, neither ventricular pacing nor ventricular-coupled pacing had a discernible influence on ventricular compliance. The results were not influenced by the functional state of the heart. The results are consistent with the position that coupled pacing has no direct effect on the relation between ventricular end-diastolic pressure and fiber length.
