324例不同部位心肌梗塞并发心律失常分析

The EKG Analysis on 324 Cases of Arrhythmis in Myocardial Infarction

324例不同部位心肌梗塞心电图检出率,以前间壁最高135例(41.66％),其次单纯下壁92例(28.39％),广泛性前壁49例(15.12％),侧壁32例(9.87％)。125例不同部位急性心肌梗塞并发一种以上心律失常102例(81.6％)。由于并发严重心律失常死亡10例(8.0％),其中在22例急性广泛性前壁心肌梗塞中有7例死亡(31.81％),下壁并正后壁及并右室3例(30.0％)。其它部位小范围单纯性心肌梗塞在住院期间均无1例死亡。表明大面积心肌梗塞并发严重心律失常是病死率最高的主原因之一。

Out of 324 cases of myocardial infarction occurring in various areae of the heart,as we had observed,there are 135 cases of myocardial infarction occurring in anteroseptal wall,which stand as high as 41.66% at the detection rate,and 92 cases occurring in inferior wall (28.39%),and 49 cases occurring in anterior wall (15.12%),and 32 cases occurring in lateral wall (9.8%).Out of 125 cases of acute myocardial infarction in various areas of the heart,102 cases,as much as 81.6% were accompanied with more than one type of abnor-mal arrhythmia of heart and 10 death cases at a rate of 8.0% were due to sever accompanying abnormal arrhythmia of heart,7 death cases caused by including extensive infarction in an-terior wall from among 22 cases of the same kind and 3·cases accompanied with acute infarction in inferior and posterior wall and right ventricular wall.All the datum show that acute generalized myocadial infarction accompanied with arrhythmia is one of the most im-portant causes that have led to the increase of the death rate from this disease.However,none of the patients with localized infarction in other small areas of the heart have ever died in the hospitalization.
