Abstract Objective To analyze the value of 12-lead real-time wearable ECG device for remote early event detection among patients at home and in primary hospitals. Methods ECGs of 20 271 subjects were collected by using 12-lead real-time wearable ECG devices at home and in primary hospitals, and transferred to the consultation center of our hospital. All of the ECG data were classified according to the degree of severity—critical, urgent and ordinary; the ECG grading results were timely notified patients themselves and their family members or primary hospitals. Critical ECG cases were followed up within 1 to 12 days. Results A total of 21 253 ECGs are enrolled into analysis. Among them, male’s ECGs account for 56.50% (12 007/21 253), slightly higher than female’s; 55.03% (11 695/21 253) of ECGs are collected from primary hospitals,slightly higher than those collected from families; 40.55% (8 619/21 253) of ECGs come from subjects with symptoms of discomfort, mainly chest tightness, chest pain and palpitation. Abnormalities are found in 66.63% (14 160/21 253) of the ECGs including 39.45% (8 385/21 253) of myocardial ischemia ECGs and 24.64% (5 237/21 253) of arrhythmia ECGs with premature ventricular contraction ECGs accounting for the highest detection rate of 5.52%. Critical ECG reports account for 0.61%(130/21 253), and serious clinical events occur in 20.21%(19 cases) of the involved 94 subjects. Conclusion The 12-lead real-time wearable ECG device can make remote early detection for arrhythmia and myocardial ischemia among patients at home and in primary hospitals, and divide remote ECGs into critical, urgent, and ordinary grades for further diagnosis. It can improve patients prognosis, and ultimately benefit patients and primary medical institutions.
