变异性心绞痛是由冠状动脉痉挛引起的一种不稳定型心绞痛,心绞痛发作时多数病人有胸闷、胸痛等症状,但也有少数部分病人症状不明显甚至缺如。有症状的病人因身体不适可能会及时就医,而症状不明显的病人就诊率很低,容易贻误病情,以至发生急性心肌梗死甚至猝死。变异性心绞痛在一般性活动甚至休息时均会发生,而且由于发作的时间短,因此常规的心电图不易记录,所以在变异性心绞痛患者的诊断过程中,12导联动态心电图相对就有明显优势,笔者对35例变异性心绞痛患者采用
Variant angina pectoris is a type of unstable angina pectoris caused by coronary artery spasm. Most patients have chest tightness, chest pain and other symptoms during the onset of angina pectoris. However, there are also some patients whose symptoms are not obvious or even absent. Symptomatic patients may be due to physical discomfort may seek medical treatment in time, and the symptoms of patients with low attendance, easy to delaying the disease, as well as acute myocardial infarction or even sudden death. Variant angina pectoris occurs during general activities and even at rest, and due to the short attack time, conventional ECG is not easy to record. Therefore, during the diagnosis of patients with variant angina, the 12-lead ambulatory electrocardiogram has relatively obvious advantages. The author of 35 cases of variant angina patients
