心电图对心源性猝死高危患者的预测价值

The Value of Electrocardiogram in Detecting Sudden Cardiac Death

心源性猝死(SCD)是心血管疾病最主要的死亡原因之一,也严重威胁着人类的健康,而早期诊断是预防SCD的关键所在。心律失常是SCD的主要原因,心电图可以对这些心律失常做出明确诊断。体表心电图对SCD相关疾病,尤其是急性心肌梗死和遗传性离子通道病具有明确的诊断价值,而且体表心电图检查具有简便易行、可重复性好的优势,所以成为检测、发现和随访可疑猝死者的重要手段。动态心电图、运动心电图等无创心电学检查中反映心脏自主神经活动的指标,对SCD也有较好的预警作用。

Sudden cardiac death（SCD）is not only the leading cause of death from cardiovascular disease,but also a serious threat to human health.Early diagnosis is the key measure of preventing such diseases.The main cause of SCD is the arrhythmia that electrocardiogram（ECG）can make definite diagnosis.ECG is also valuable for those diseases associated with SCD,such as acute myocardial infarction and genetic ion channel disease.Because operated simply,ECG plays an important role in detecting and diagnosing SCD.Other non-invasive cardiac electrical test,such as Holter and exercise ECG,may be valuable to detect SCD.
