## Abstract The objective of this study was to determine the effects of repetitive ischemia on myocardial oxygen tension (pO~2~), consumption, and delivery in crystalloid normoperfused (perfu‐sion pressure > 70 mmHg) and hypoperfused (perfusion pressure ˜50 mmHg) constant flow isolated rat hearts.
The purpose of this study was to examine the feasibility of quantifying myocardial blood flow (MBF) and rate of myocardial oxygen consumption (MVO(2)) during pharmacologically induced stress without using a contrast agent. The former was measured by the arterial spin labeling (ASL) method and the la
