Abstract: Purpose. To evaluate the accuracy of the QRS complex detectorof the Medicom-combi complex for daily monitoring of ECG and blood pressure using the MIT-BIH ECG signal test database in accordance with the requirements of GOST R IEC60601–2–47–2017, 30324.2.47–2012. Materials and methods. During the tests, the operation of the detector was evaluated using the MIT-BIH Arrhythmia Database, containing 48 records of 30 minutes each. Each selected QRS complex was assigned one of the following types: N (supraventricular complex, normal QRS complex, including bundle branch block), V (ventricular complex), U (complex that experts find difficult to determine) and A (artifact). Rates of sensitivity (Sen), specificity or positive predictive rate (PPR), and overdiagnosis (FPR) were determined. Results. The sensitivity of the QRS complex detector of the Medicom-combi complex for daily monitoring of ECG and blood pressure was 99,98%, and the specificity was 99,87%. The sensitivity of determining ventricular complexes was 99,97%, the specificity of determining ventricular complexes was 99,64%. Overdiagnosis of ventricular complexes does not exceed 0,03%. Conclusion. The Medicom-combi complex for daily monitoring of ECG and blood pressure, designed for long-term ECG monitoring, has sufficient sensitivity and specificity for analyzing Holter ECG recordings, as well as identifying ventricular ectopic complexes.
