采用信息叠加技术检测冠心病204例、心肌炎26例、高心病18例、肺心病8例、风心病9例、甲亢性心脏病2例、心肌病及预激症侯群各1例共269例的心室晚电位(VLP),观察不同类型心脏病晚电位检出率及其与室性心律失常的关系和晚电位阳性标准。冠心病中陈旧性心梗(OMI)、心绞痛和无痛性心肌缺血 VLP 检出率分别为38.5%、15.5%和8.25%,其他类型心脏病 VLP 检出率为12.3%,其中肺心病20%、风心病14.3%、高心病5.6%、心肌炎11.5%。心肌梗塞伴室性心律失常 VLP 检出率55%,非心梗的室性心律失常为16.6%,简单室早为4.3%。木文 VLP 阳性36例,三项指标异常10例(27.7%),二项指标异常26例(72.3%)。
The information superposition technique was used to detect coronary heart disease in 204 cases, myocarditis in 26 cases, hyperglycemia in 18 cases, cor pulmonale in 8 cases, rheumatic heart disease in 9 cases, hyperthyroidism heart disease in 2 cases, cardiomyopathy and pro-inflammatory syndrome in 1 case, a total of 269 cases Of ventricular late potential (VLP), observe the different types of heart disease late potential detection rate and its relationship with ventricular arrhythmias and late potential positive standard. Coronary heart disease in old myocardial infarction (OMI), angina and painless myocardial ischemia VLP detection rates were 38.5%, 15.5% and 8.25%, other types of heart disease VLP detection rate was 12.3%, of which pulmonary heart disease 20 %, Rheumatic heart disease 14.3%, heart disease 5.6%, myocarditis 11.5%. Myocardial infarction with ventricular arrhythmia VLP detection rate of 55%, non-myocardial infarction ventricular arrhythmia was 16.6%, simple room as early as 4.3%. There were 36 positive cases of VL in VL, 10 (27.7%) were abnormal in 3 indicators and 26 (72.3%) were abnormal in 2 indicators.
