DIAGNOSTIC TECHNIQUE FOR AUTONOMIC CARDIAC NEUROPATHY IN PATIENTS WITH TYPE 2 DIABETES MELLITUS Russian patent published in 2013 - IPC A61B5/452 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, particularly endocrinology and diabetology. There are involved examining heart rate variability (HRV) followed by spectroscopic analysis and functional testing. Those are added with determining non-linear values: deterrent fluctuation analysis (DFA) and approximated entropy (ApEn). If observing the initial amplitude decay of the HRV spectral components - VLF less than 30 points, LF less than 15 points, HF less than 15 points, DFA more than 0.7, ApEn less than 180, lack of functional response - autonomic cardiac sympathovagal neuropathy is diagnosed. If observing the normal amplitude of the HRV spectral component -VLF more than 30 points, low LF values less than 15 points, HF less than 15 points, DFA more than 0.7, ApEn less than 180, lack of functional response LF, HF - autonomic cardiac vagal neuropathy is diagnosed. If observing the initially normal amplitudes of the HRV spectral component -VLF more than 30 points, LF more than 15 points, HF more than 15 points, DFA more than 0.7, ApEn more than 180, lack of functional response LF, HF - autonomic cardiac subclinical neuropathy is diagnosed.

EFFECT: method enables early diagnosing and typing of autonomic cardiac neuropathy for the purpose of specifying a therapeutic approach.
