左主干闭塞所致急性心肌梗死的心电图特点及临床分析

Left branch unenlightened result acute cardiac arrest＇s electrocardiogram characteristic and clinical analysis

大量临床资料表明，心电图改变对急性心肌梗死相关的冠状动脉病变定位和程度的判断有很大价值，其中急性左主干（LM）闭塞导致的急性心肌梗死（AMI）是急性冠脉综合征中最严重的病变，病情凶险，死亡率高，仔细观察患者心电图常有特征性改变，临床可据此帮助捡出该类患者，对选择治疗方案及评估病人的预后都至关重要，本篇分析110例经冠脉造影证实急性左主干（LM）闭塞导致的急性心肌梗死，分析其临床特点并对左主干病变的心电图与单纯前降支心肌梗死的心电图作比较，以求总结其心电图特点，并且分析治疗方法及预后。

The massive clinical material indicated that the electrocardiogram change has the very great value to the acute cardiac arrest related coronary artery pathological change localization and the degree judgment, the acute left branch .（LM） causes unenlightened the acute cardiac arrest （AMI） is in the acute crown arteries syndrome the most serious pathological change, the condition bad risk, the mortality rate is high, observes the patient electrocardiogram common characteristic value change carefully, clinical may help to pick this kind of patient according to the above, to chooses the therapeutic schedule and appraises patient＇s prognosis to be very important, this analyzes 110 examples after the crown arteries radiography to confirm the acute left branch （LM） causes un- enlightened the acute cardiac arrest, analyzes its clinical characteristic and to the left branch Before pathological changers electrocar- diogram and pure, falls cardiac arrest＇s electrocardiogram to do compares, summarizes its electrocardiogram characteristic in order to, and analysis method of treatment and prognosis.
