动态心电图(DCG)也称活动心电图(AEG)或Holter氏心电监测,是美国Holter首创并于1961年应用于临床。可记录日常活动和静息下的心电图。能提高各类心脏病心律失常的检出率,并预防猝死;提供诊断缺血性心脏病和病窦综合征(SSS)的资料;评价抗心律失常药和抗心绞痛药的疗效;估价心脏起搏器功能。DCG为较理想的无创伤性检查。国外已普遍应用。仪器构造和使用DCG由磁带记录器和心电扫描分析仪组成。1.磁带记录器为小型携带式,由电池供电,重0.45～0.9kg,监测电极为银——氯化银电极,
Dynamic electrocardiogram (DCG), also known as active electrocardiogram (AEG) or Holter’s ECG, is Holter pioneered by the United States and in 1961 for clinical use. Can record daily activities and resting ECG. Can improve the detection rate of various cardiac arrhythmias and prevent sudden death; provide information on the diagnosis of ischemic heart disease and sick sinus syndrome (SSS); evaluate the efficacy of anti-arrhythmic drugs and anti-anginal drugs; Pulse function. DCG is the ideal non-invasive examination. Foreign has been widely used. Instrument Construction and Use The DCG consists of a tape recorder and an ECG scan analyzer. 1. Tape recorder for small portable, battery-powered, weighing 0.45 ~ 0.9kg, the monitoring electrode is silver - silver chloride electrode,
