Myocardial blood flow in pacing-induced angina.
Current methods of measuring myocardial blood flow using 133xenon have failed to separate normals from patients with ischemic heart disease at rest. In the present study such a separation was attempted by utilizing pacing-induced tachycardia (PIT) to stress the myocardium. 133Xenon was injected into the left coronary artery to measure blood flow in 27 patients at rest and during pacing-induced ...
متن کاملMyocardial oxidative metabolism, blood flow and efficiency in rapid pacing induced heart failure in dogs.
PURPOSE Heart failure is the final common pathway for most forms of heart disease, and is characterized by a reduced energy status. Myocardial oxygen consumption (MV02) is closely related to the main determinants of systolic function (heart rate, pressure and contractility). The aim of the study was to compare myocardial blood flow, metabolism and mechanical efficiency in rapid pacing induced h...

متن کاملIncreased Regional Myocardial StiEfness of the Left Ventricle During Pacing-induced Angina in Man
The left ventricular diastolic pressure-volume.relationship shifts upward during angina, but why this happens is not known. To assess regional myocardial stiffness, we studied 12 patients who.had coronary artery disease using simultaneous left ventricular micromanometer pressure recording and Mmode echocardiography before and during angina induced. by pacing tachycardia. All patients had twoor ...
