目的 探讨心电图有缺血分布区的病理性Q波的病因及临床意义。方法 对30例因胸痛、心前区不适、心电图有缺血分布区的病理性Q波患者(已确诊为心肌梗死者、心力衰竭、预激综合征除外)行冠状动脉造影检查。结果 肥厚型心肌病15例,冠状动脉正常1例,先天性左房室瓣前叶裂合并轻度左房室瓣返流1例,冠心病7例(1例为高血压合并冠心病) ,单纯高血压7例(均有心肌肥厚)。结论 当心电图出现有缺血分布区的病理性Q波,而患者无确切的心肌梗死病史,应先行心脏彩色超声检查;只有在有典型的心绞痛患者,才应行冠状动脉造影术。
Objective To investigate the etiology and clinical significance of pathological Q wave in ischemic distribution of electrocardiogram. Methods Thirty patients with pathological Q wave due to chest pain, precordial discomfort and ischemic electrocardiogram were examined by coronary angiography (diagnosed as myocardial infarction, heart failure, and WPW syndrome). Results Fifteen cases of hypertrophic cardiomyopathy, one case of normal coronary artery, congenital anterior mitral valve rupture and mild left atrioventricular valve regurgitation in 1 case, 7 cases of coronary heart disease (1 case of hypertension with coronary heart disease) Hypertension in 7 cases (both myocardial hypertrophy). Conclusion When there is pathological Q wave in the ischemic area of ECG, and the patient has no definite history of myocardial infarction, heart color sonography should be performed first. Coronary angiography should be performed only in patients with typical angina pectoris.
