Intraventricular Pressure and the Distribution of Coronary Blood Flow

摘要: The subepicardial: subsendocardial ratio of Rb86 contents was measured and used as an index the distribution coronary blood flow to more superficial deeper layers canine myocardium. In normally beating heart, level intraventricular pressure did not exert any detectable influence upon this contents. fibrillating or in ischemic (and presumably non-beating) region on other hand, increased progressively raised. It is concluded, therefore, that exerts a significant myocardium only regions which are normally.
