问:1.我们观察了不少病人,临床上无冠心病证据,心电图示无心肌缺血,不少还是十来岁的儿童,可高频心电图阳性。即高频心电图阳性率高,如何解释?2.应用一些药物治疗前后观察高频心电图变化,效果不十分理想。3.晚电位阳性率低。(解放军第230医院张守仁)答:1.高频心电图(HFECG)阳性率(比晚电位和普通心电图)高是其特点和优点。HFECG不是病因诊断,仅是病理形态或生理机能(电活动)异常的反映。只要任何心脏疾病产生心肌斑块状坏
Q: 1. We observed a lot of patients, clinically no evidence of coronary heart disease, electrocardiogram showed no myocardial ischemia, many children are still ten years old, positive HF electrocardiogram. That high-frequency electrocardiogram positive rate, how to explain? 2. Use of some drugs before and after treatment to observe changes in high-frequency ECG, the effect is not very satisfactory. 3. late potential low positive rate. (People’s Liberation Army 230 Hospital Zhang Shouren) A: 1. High-frequency electrocardiogram (HFECG) positive rate (than the late potential and general electrocardiogram) is its characteristics and advantages. HFECG is not an etiological diagnosis but only a reflection of abnormalities in pathology or physiology (electrical activity). As long as any heart disease produce myocardial plaque bad
