Effect of acute volume load on refractoriness and arrhythmia development in isolated, chronically infarcted canine hearts

In normal isolated, perfused canine ventricles, increased ventricular volume leads to shortening of refractoriness. To test the hypothesis that myocardium within an infarction zone is more susceptible to volume-induced changes in refractoriness than is normal myocardium, we measured strength-interva...
