三.动态心电监护系统常规心电图是病人在医院中静卧情况下由心电图仪记录下来的心电活动(心电图)。正如前面所指出的,在体表的几个点上记录几秒钟到十几秒钟的心电,只能获取很少有关心脏状态的信息。体表电位标测系统可以获得心电的空间全信息,比常规心电图要好得多,但它也只能记录几秒钟的心电信息。因为心脏的工作是受许多因素的影响的,特别是环境(如过热、过冷、噪声等)和人的精神状态(如悲哀、兴奋、愤怒、惊恐、疲劳、烦 Three. Holter monitoring system conventional ECG is the case of patients in the hospital when lying down by the electrocardiograph recorded ECG (ECG). As noted earlier, recording a few seconds to tens of seconds of ECG at several points on the body surface can only give very little information about the state of the heart. Surface potential mapping system can get the full information of the ECG space, much better than the conventional ECG, but it can only record a few seconds of ECG information. Because the work of the heart is affected by many factors, especially the environment (such as overheating, cold, noise, etc.) and mental state (such as sadness, excitement, anger, panic, fatigue, annoying
