微型心电记录器(MECGR)是一种由受检者携带,其本人或他人操纵的实时记录一短程心电活动的超小型记录器。本文就其临床应用问题作一简要介绍。一、各种国产MECGR的主要异同点共同点:①可记录不同环境和状态下的心电动态变化;②由受检者根据病情,实时记录最为可疑的短暂心电活动异常;③操作技术简单,回放只需一台普通心电图机。异点:①记录的心电信息量不同,从40～80秒不等;②抗干扰性不同;③形状,大小不同,以致携带方便程度不一。二、MECGR与Holter的比较①总信息量较小,不能反映24h总心率、最高和最低心率;③不能显示心率和ST-T的动态趋势;③单通道记录;④对无症状受检者
The Micro Electrocardiograph (MECGR) is an ultraminiature recorder that is carried by a subject and recorded by himself / herself or by someone in real time to record a short-range ECG activity. This article on its clinical application of a brief introduction. First, all the major differences between the domestic MECGR similarities and differences: ① can record the dynamic changes of the state of the environment under different conditions; ② subject according to the disease, real-time recording of the most suspicious transient ECG abnormalities; ③ simple operation technology , Playback just a normal ECG machine. Different points: ① ECG recorded different amount of information, ranging from 40 to 80 seconds; ② different anti-interference; ③ different shapes and sizes, resulting in different degrees of ease of carrying. Second, compare the MECGR and Holter ① total amount of information is small, can not reflect the total heart 24h, maximum and minimum heart rate; ③ can not show the dynamic trend of heart rate and ST-T; ③ single-channel record; ④ asymptomatic subjects
