摘要

Method and device for long-term variability monitoring of cardiovascular parameters based on registered electrocardiogram (ECG) and pulse wave signals provide digitalization of a patient's ECG and pulse wave signal, followed by registration of R-peaks of ECG signal and basing on these also formation of NN series, pulse wave raising front detection with delay time calculation and basing thereupon also formation of delay time NN series, QT interval calculation and basing thereupon also formation of QT interval NN series which are followed by time and frequency variability analysis of all the formed NN series and in pairs by time and frequency variability correlation analysis.
