Distinguishing ischemic from fibrotic myocardium during ventriculograpy by means of physiological potentiation.
Physiological potentiation during ventriculography is more helpful than the routine ventriculogram in predicting postoperative ventricular function. The authors describe a control device which allows the operator to flexibly program a pacing stimulus, thus making it possible to obtain both a resting beat and an optimum potentiated beat during a single ventriculographic study.
