METHOD FOR EVALUATING ARTERIAL HYPERTENSION TREATMENT EFFECTIVENESS IN 30-60 YEARS OLD PATIENTS Russian patent published in 2007 - IPC A61B5/452 

FIELD: medicine.

SUBSTANCE: method involves measuring hemodynamic parameters of organism. Slow cardiac rhythm oscillations are recorded before beginning the treatment. Wave frequencies are recorded in bandwidths of UVLF 0.025 Hz, VLF0.026-0.075 Hz, LF 0.076-0.15 Hz, HF 0.16-0.5 Hz, with spectral analysis being done and spectral power density and cardiac rhythm variability power density being determined next in said bandwidth intervals. Total spectral cardiac rhythm power in the intervals is calculated and cardiac rhythm spectrum power per cent distribution of said frequency bandwidth ranges in cardiac rhythm spectrum. Therapy is administered using one of antihypertensive drug groups. Slow cardiac rhythm oscillations are recorded and analyzed 2 weeks later in the same frequency bandwidths. 1 measurement unit of value under study / Hz is taken for 1 point. Total spectral cardiac rhythm power density being evaluated in 30-120 points, cardiac rhythm variability power density being evaluated in 16-60 points in HF bandwidth, LF - 12-61 points, VLF - 6-19 points UVLF - 1-7 points, oscillation power spectrum density per cent distribution within cardiac rhythm spectrum being evaluated as follows: HF - 31-55%, LF - 26-43%, VLF - 11-22%, UVLF - 2-7%, effective treatment is considered to be the case. Cardiac rhythm variability power deviation from the values of frequency bandwidth HF - 16-60 points in, LF - 12-61points, VLF - 6-19 points UVLF - 1-7 points, towards increase or reduction and when oscillations spectrum power density per cent distribution inside of said cardiac rhythm spectrum from the values of HF - 31-55%, LF - 26-43%, VLF - 11-22%, UVLF - 2-7%, the treatment is considered to be to be ineffective and prescribed drug dose is increased, combined therapy is advised, or and antihypertensive drug group is changed.

EFFECT: high accuracy and accelerated evaluation method.
