BACKGROUND
This study was performed in attempt to draw a correlation between the percentage of myocardial infarction across the left ventricular wall and changes in the QRS complex in the epicardial ECG in a primate model of ischemia-reperfusion injury.
METHODS
Myocardial infarction was induced in six baboons by ligating the left anterior descending coronary artery for 2h. Using ECG leads, the presence of Q and R waves was recorded along with their associated left ventricular wall thickness.
RESULTS AND CONCLUSIONS
The results indicate that Q-wave development and R-wave loss can be correlated with depth of infarct.
背景
本研究旨在探讨在灵长类动物缺血再灌注损伤模型中，左心室壁心肌梗死百分比与心外膜心电图QRS波群变化之间的相关性。
方法
通过结扎左前降支冠状动脉2小时，在6只狒狒中诱导心肌梗死。使用心电图导联，记录Q波和R波的存在及其相关的左心室壁厚度。
结果与结论
结果表明，Q波的出现和R波的消失与梗死深度相关。
