Abstract Objective To investigate the clinical value of remote monitoring system in diagnosing patients with arrhythmia and ST-T change.Methods A total of 78 patients with heart diseases or heart symptoms were undergone 12 lead electrocardiogram(ECG) and remote ECG monitoring examination; 42 out of 78 cases received Holter examination．The recall rate of remote ECG monitoring, 12 lead ECG and Holter in the diagnosis of arrhythmia and ischemic ST-T change was compared．Results There were significant differences in the detection of arrhythmia and ST-T changes between remote ECG monitoring and 12 lead ECG (79.5% vs 59.0%,P<0.05 for arrhythmia; 17.9% vs 7%, P<0.05 for ST-T change). There was no significant difference in the detection of arrhythmia and ST-T changes between remote ECG monitoring and 24-hour Holter （81.0% vs 71.4%,P>0.05 for arrhythmia; 23.8% vs 16.7%,P>0.05 for ST-T changes）. Among the 42 patients with Holter, 34 patients with arrhythmia were recorded by remote ECG monitoring while 30 patients with arrhythmia were recorded by Holter.No significant difference was found between these two methods(81.0％vs71.4%,P>0.05). 10 patients with ischemic ST-T change were recorded by remote ECG monitoring (23.8%), insignificantly different from that by ECG (7/42, 16.7%, P>0.05).Conclusion Compared with 12 lead ECG, remote ECG monitoring shows higher detection rate in diagnosing arrhythmia and ischemic ST-T changes. While compared with Holter, remote ECG monitoring failed to diagnose arrhythmia and ischemic ST-T changes.
