Introduction: In the Xinjiang-Uygur region of China, there are two tribes; one is a long-lived tribe, Uygur in Hotan, and the other is a short-lived tribe, Kazakh. We have conducted epidemiologic studies on these tribes but forced to limit the number of subjects because precision medical instruments are hard to carry to the locations due to the harsh climate. HCG-801 (Omron Healthcare Co.) is a portable ECG monitor for home use. It records approx. 30 seconds of ECG measurement and displays the waveform, HR and a result message on the LCD after each measurement. Since it is compact, HCG-801 is easy to carry and take ECG data from a large number of people. Thus we used HCG-801 for the epidemiologic studies on the Kazakh tribe and evaluated the accuracy comparing with a 12-lead ECG device.

Method: The target groups consist of 146 subjects\'7badults (M:49, F:47) aged 30-35, children (M:28, F:22) aged 9-10 \'7d of the Kazakh tribe. In the study we asked the subjects to record an ECG on their own with HCG-801 at V4 lead after we completed 12-lead ECG monitoring.

Results: (1) Each parameter (R-R interval , PQ interval, QRS width, QT/QTc interval, R-wave height, S-wave depth and T-wave height) of the ECGs with HCG-801 had significant correlation with the one of the 12-lead ECG at lead V4. (2) 71% of the message contents of HCG-801 are consistent with the doctor's finding from the 12-lead ECG. The artifacts in the ECGs with HCG-801 caused false positive mainly.

(3) 95% of the doctor's finding on the waveform with HCG-801 matched the one from the 12-lead ECG. The discordant data are; 5 cases arrhythmia during measurement with exclusively either HCG-801 or the 12-lead ECG device no anomalies with HCG-801 whereas 3 cases of anomalies in other lead than V4 with the 12-lead ECG device.

Conclusion: HCG-801 can be certainly utilized for epidemiologic research besides home use. The information from the ECGs except artifacts is very beneficial.
