Abstract Objective To discuss the clinical value of portable remote ECG monitoring for arrhythmia and heart rate during outpatients recovery of external counterpulsation(ECP).Methods For the enrolled 268 outpatients, the results of portable ECG monitoring and blood pressure monitoring were compared before, during and after ECP, and also compared with the results recorded by routine ECG.Results We collected 1 658 strips of ECGs in all monitored before, during and after ECP, including 1 576 valid ones, accounting for 95.1%. Arrhythmia was detected out of 133 strips of ECGs by portable remote ECG monitoring, with a detection rate of 25.4%(68/268), while 33 cases with arrhythmia were detected by routine ECG, with a detection rate of 12.3% (33/268). The difference of detection rates in the two methods was statistically significant(P<0.01). After the treatment of ECP, the patients heart rates[(68.84±10.79) beats/min] were slowed down than before[(74.04±11.48) beats/min], with statistically significant difference (P<0.001). After the treatment of systolic blood pressure, their heart rates[(124.99±12.68) mmHg] were slowed down than before[(129.67±12.17) mmHg], with statistically significant difference (P<0.001). After the treatment of diastolic blood pressure, their heart rates[(72.73±7.19) mmHg] were slowed down than before[(74.06± 8.23) mmHg], with statistically significant difference (P<0.01).Conclusion The portable remote ECG monitoring can be applied in observing the changes of heart rate and recording electrocardiosignals of arrhythmia. The method proves to be convenient and practical. The detection rate of arrhythmia is higher than that of routine ECG examination.
