METHOD FOR MEASURING HEART CYCLE PHASES

摘要

FIELD: medicine. SUBSTANCE: method involves additionally using the second derivative of radial artery sphygmogram built by applying numeric differentiation based on Tikhonov regularization method. Specific features are used for determining heart cycle phases in systole and diastole with higher degree of accuracy when compared with heart cycle phase measurement method based on speed kinetocardiogram. EFFECT: enhanced accuracy of measurements.
