宽频带心电图(Wide Frequency ECG),又称高频心电图(High FrequlencyECG)。早在1917年有人提到心肌病时电压下降,QRS 波上出现高频切迹,当时由于条件限制未能录到这种高频成份。直到1952年 Langner 氏才以宽带在冠心病患者中录到不少这种成份。从那以后国外对宽频带心电图的研究逐渐增多,国内近几年来亦有研究及报导。据现有国内外资料及观察结果均认为宽频带心电图对某些心血管疾病的诊断确有一定价值。本文拟通过对正常人、冠心病、高血压性心脏病以及心肌炎、心肌病等278例的宽频带心电图的
Wide-band ECG (Wide Frequency ECG), also known as high-frequency electrocardiogram (High FrequelcyECG). As early as 1917, it was mentioned that the voltage dropped during cardiomyopathy, and the high frequency notch appeared on the QRS wave. At that time, the high frequency component was not recorded due to the conditions. Until 1952 Langner’s broadband in patients with coronary heart disease recorded a lot of this ingredient. Since then, foreign studies on broadband ECG have gradually increased, and research and reports have also been made in China in recent years. According to the existing data both at home and abroad and the results of the observation, it is believed that the diagnosis of certain cardiovascular diseases by broadband ECG has a certain value. This article intends to pass on normal, coronary heart disease, hypertensive heart disease and myocarditis, cardiomyopathy and other 278 cases of broadband ECG
