The incidence of major abnormal ECG were 7.3% for STT changes, 5.6% for sinus tachycardia, 4.4% for sinus arrhythmia, 3.4% for ventricular premature beats, 2.0% for bundle branch block and 1.8% for atrial premature beats; Apart from preexcitation syndrome, the incidence of abnormal ECG for male was higher than that of female;Most of abnormal ECG increased with age. A few abnormal ECG such as sinus tachycardia, sinus arrhythmia, sick sinus syndrome decreased with age. The incidence of sinus bradycardia and preexcitation syndrome were bail shape with age. Half of abnormal ECG adults had at least two abnormal ECG, such as STT changes combined with ventricular premature beats or bundle branch block.

异常心电图较多的有STT改变（7.3%）、窦性心动过速（5.6%）、窦性心律不齐（4.4%）、室性早搏（3.4%）、束支传导阻滞（2.0%）、房性早搏（1.8%）；除预激综合征外，其他异常心电图都是男性多于女性；多数异常心电图的检出率随年龄增加而增加，但窦性心动过速、窦性心律不齐、病窦综合征随年龄增加而减少，窦性心动过缓和预激综合征的检出率与年龄呈&杓形&关系；在异常心电图人群中，有约1/2的人合并2种或2种以上的心电图改变，最常见的是缺血性STT改变合并室性早搏或传导阻滞。

The results were analyzed with the statistical software package spss10.0.results ①between two groups,there was no significant difference about the affection of age,sex and the destribution and location of aneurism on prognosis outcome(p＜0.05).however,the grading of hunt hess and fisher in group a(gos＞3) showed significantly lower than in group b(gos≤3),（p＜0.001）;② there was no significant difference in the frequency of heart rate, st elevation, st depression,t wave inversion,u wave inversion and ventricular arrhythmia(p＞0.05).the frequency of abnormal q wave, supraventricular arrhythmia and the ecg scores in group a showed significantly lower than in group b （p＜0.05,p＜0.001）;③the ecg scores was the most powerful multivariate risk stratified(ecg ≥5 vs ecg＜5; p=0.002,or=0.010,95%ci 0.001~0.173).conclusion the ecg score, a new and simple method of semi quantification, was a powerful risk predictor for patients with sah.

应用spss10.0 统计包分析结果。结果①在年龄、性别、动脉瘤生长部位影响动脉瘤性sah预后方面，两组病例无明显差异（p＞0.05）。而按sah后hunt hess分级和fisher分级，gos＞3病例的分级要明显低于gos≤3的病例的分级（p＜0.01）；②两组在心率、st段抬高、st段压低、t波倒置、u波倒置、室性心律失常出现的频率无明显差异（p＞0.05）；在异常q波和室上性心律失常出现频率及心电图评分方面，gos＞3的组别明显低于对照组（p＜0.05，p＜0.001）；③心电图评分是sah患者预后最显著影响的变量（p=0.002，or=0.010，95%的可信区间0.001~0.173）。结论心电图评分作为一种新型、简便的半定量方法，能有效的预测蛛网膜下腔出血病人的预后。关键词：心电图；预后；评分；蛛网膜下腔出血

Results For the hypertrophies in left or right atrium or ventricle or doule atriums or ventricles, the ECG plus VCG method had a high sensibility and accuracy.For the hypertrophies in right atrium and double atriums,the only ECG method had the same sensibility with the ECG plus VCG method.For the righ ventricle, the only VCG method had the same sensibility with the ECG plus VCG method.For the specificity, the three methods almost had the same value.ECG plus VCG method combining the clinical material could improve the acuracy in the diagnosis of atrial and ventricular hypertrophies.

结果：ECG和VCG联用对左心房、右心房、左心室、右心室、双心房、双心室肥大诊断的敏感性及准确性最高，ECG单独应用及ECG和VCG联用对右心房及双心房肥大的诊断敏感性相同，VCG单独应用和ECG和VCG联用对右心室肥大的诊断敏感性相同；3种方法对心房、心室肥大诊断的特异性相近；ECG和VCG联用诊断心房、心室肥大时结合临床资料可提高准确性。
