摘要
急性下壁心肌梗塞ST段抬高往往存在对应导联ST段压低。梗塞区ST段抬高的峰值与对应导联ST段谷值之间有无相关性主要与压低的ST段恢复时间有关,半月以内恢复者有显著相关性,半月以上恢复者则无相关性。由此提示:急性下壁心肌梗塞对应导联ST段的压低是广泛心肌组织缺血以至坏死的反应。此外,梗塞区ST段抬高峰值与血清酶CPK显著相关,与GOT有相关性而与LDH_1无相关性。
The ST segment elevation in acute inferior infarction was usually accompanied by the reciprocal ST segment depression. Whether there was a correlation between the peak value at the elevated ST segment in infarction area and the valley value at the reciprocal depressed ST segment was mainly related to the time lasted for the restoration of depressed ST segment. If the restored time was within 15 days, a significant correlation could be observed; if it was beyond 15 days no correlation existed then, It was revealed that the reciprocal ST segment depression happened in acute inferior infarction was a reaction responded to extensive ischemia and even necrosis. Besides there was also a significant correlation between the peak value of elevated ST segment and serum CPK. A correlation was also existed between the peak value of ST segment and GOT as for LDH_1, it was not true.
