心电图分析是一种很有价值的心血管检查方法,但一欢十二导程常规心电图描记中所记录的心搏一般少于100次,而在此记录期间发生心律失常的几率是不大的。尤其是一些阵发性心律失常,即使病人有自觉症状,但在做心电图时却很难捕获。 1957年美国Holter实验室报导,研究出一种用磁带记录器对正常活动状态下的病人作长时期连续心电图记录、然后作快速分析的方法。这种长时间连续记录的心电图称为动态心电图(Dynamic Electrocardiogram),简称DCG。习惯上也将这种心电图记录分析 ECG analysis is a valuable cardiovascular test, but a stroke of twelve leads routinely records fewer than 100 beats in conventional electrocardiograms, and the odds of arrhythmia during this recording are modest . Especially paroxysmal arrhythmia, even if the patient has symptoms, but it is difficult to capture ECG. Holter Laboratory in the United States in 1957 reported the development of a magnetic tape recorder for patients with normal activity for a long period of continuous ECG records, and then for rapid analysis. This prolonged continuous recording of the cardiogram called dynamic electrocardiogram (Dynamic Electrocardiogram), referred to as DCG. Traditionally this ECG records analysis
