| Popis: | Changes in total and regional left coronary blood flow in response to ventriculography were studied using electromagnetic and microsphere techniques. Correlation of coronary flows by these methods showed excellent agreement (r = 0.947). Ventriculography produced a characteristic triphasic response in total flow and in endocardial/epicardial perfusion ratios. Changes in coronary flow can be explained as a result of hypotension and vasodilatation. |
