Atrial pacing may differentiate normal from myopathic LV responses; hypothesis-generating and should not yet change practice.
Does right atrial pacing-induced change in stroke volume help differentiate normal from abnormal left ventricular function?
Atrial pacing can be used to characterize left ventricular function and clearly separates normal from abnormal myocardial responses based on stroke work and LVEDP changes.
Joseph W. Linhart (1971) studied this question.
