Abstract
Objective To evaluate the efficacy,reliability and accuracy of a portable 12-lead ECG device compared to a conventional 12-lead ECG device.Methods We enrolled 40 healthy volunteers and 110 patients who received inpatient treatment in Department of Cardiovascular Center,Beijing Tongren Hospital,Capital Medical University from July to October 2016.ECG monitoring was performed at the same time in both groups by the portable 12-lead ECG device and the conventional 12-lead ECG device,respectively.The automatically measured values of heart rate (HR),width of PR interval,QRS interval,QT interval,and corrected QT (QTc) interval monitored by the two types of devices were recorded and compared.And the diagnostic accuracy of the two types of devices was compared.Results The HR and width of QTc interval on the ECG monitored by the two types of devices were significantly different (P ＜ 0.05),while the width of PR interval,QRS interval and QT interval on the ECG were not (P ＞ 0.05).The monitoring results for the healthy controls,patients with atrial fibrillation + atrial flutter,patients with acute ST-segment elevation myocardial infarction (STEMI),patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) + unstable angina pectoris,patients with Ⅱ degree atrioventricular block + Ⅲ degree atrioventricular block and patients with other types of cardiac diseases by the two types of devices were similar (P ＞ 0.05).Conclusion The portable 12-lead ECG device monitoring results show good accuracy and reliability,and they are basically similar to the conventional 12-lead ECG device monitoring results.Therefore,this portable 12-lead ECG device could be widely applied in the future.关键词
