The relationship between the magnitude of epicardial ST-segment elevation and intramyocardial oxygen tension after coronary artery ligation was examined in 11 dogs at various coronary perfusion pressures. The ST map significantly reflected local intramyocardial oxygen tension, and the level of coronary perfusion pressure proved to be an important determinant of both local myocardial oxygen balance and the magnitude of ischaemic injury.
在11只犬身上,于不同冠状动脉灌注压力下,研究了冠状动脉结扎后心外膜ST段抬高幅度与心肌内氧张力之间的关系。ST图显著反映了局部心肌内氧张力,冠状动脉灌注压力水平被证明是局部心肌氧平衡和缺血性损伤幅度的重要决定因素。
