METHOD FOR DIAGNOSING CARDIOVASCULAR SYSTEM OPERATION RHYTHM DISORDERS Russian patent published in 2003 - IPC

FIELD: medicine. SUBSTANCE: method involves recording patient electrocardiogram. Mean values over one hour long periods of the readings like RR- interval value mean in a sample, SDNN - mean square deviation of RR-intervals under study, rMSSD - root mean square deviation of sequential RR-intervals difference values. Local indices for these values are calculated as one hour period mean values ratio for the preceding hour and for the following hour. The found index values are used for building discriminant function which values are compared to the function value on normal electrocardiogram. EFFECT: high reliability of diagnosis. 2 cl, 3 dwg
