Abstract:

Objective To explore the diagnostic value of a wearable flexible patch ECG instrument in arrhythmia, the alarm situation during clinical application, patient satisfaction and safety. Methods A total of 1 443 subjects wore flexible patch ECG and conventional dynamic ECG (control) for 24 h to test the validity and consistency of arrhythmia diagnosis, and counted the alarm of remote ECG and the occurrence of related adverse events during the wearing of the instrument. Results There were 987 cases of arrhythmia detected by flexible patch ECG and 992 cases by conventional dynamic ECG. The total coincidence rate of arrhythmia diagnosis was 98.7%. The mean heart rate was measured by flexible patch ECG (75.4±11.4) times/min, conventional dynamic heart rate (71.5±12.1) times/min, the intra-group correlation coefficient (ICC) of 2 instruments was 0.892 (95%CI: 0.537-0.956), with good repeatability. The correct alarm rate of flexible patch ECG was 100%. The incidences of skin pruritus (0.28% vs.1.32%), skin allergy, redness and swelling (0.14% vs. 0.69%) and electrode strip shedding (0 vs.0.28%) during wearing the flexible patch electrocardiogram were lower than those of the conventional holter electrocardiogram (P<0.05). Conclusion The flexible patch ECG has few adverse reactions, high comfort, good safety and clinical applicability.
