FIELD: medicine. ^ SUBSTANCE: method involves recording and analyzing electrocardiogram with PQ, QRS, QT intervals estimation and deviation from reference values being detected. P, Q, R, S, T waves taken from basic I, II, III and amplified aVR, aVL, aVF leads are additionally studied. The deviations showing more than 25% increase or reduction in amplitude and/or polarity, and/or wave shape changes are detected. Five or more deviations being observed, myocardial dystrophy is to be diagnosed. The following values are taken as reference values for P, Q, R, S, T waves. PI=(0.04±0.008)H; PII=(0.18±0.01)H; PIII=(0.15±0.05)H; QI=(0.15±0.03)H; QII=(0)H; QIII=(0)H;RI=(0.15±0.02)H; RII=(0.33±0.05)H; RIII=(0.35±0.05)H; SI=(0.18±0.04)H; SII=(1.40±0.08)H; SIII=(1.43±0.07)H; TI=(0.075±0.013)H; TII=(0.52±0.05)H; TIII=(0.51±0.05)H, where H is the amplitude corresponding to control distortion at voltage of 1 mV; PI, PIII, QI, QII, RI, RII, SI; SII, SIII, TI, TII, TIII are the P, Q, R, S, T-wave amplitudes in healthy animal, respectively, in I, II, and III basic leads. ^ EFFECT: high reliability of diagnosis. ^ 7 dwg, 2 tbl |
