ELECTROCARDIOGRAPHIC METHOD FOR DIAGNOSING NEWBORN CALVES MYOCARDIAL DYSTROPHY Russian patent published in 2007 - IPC A61B5/468 A61B5/472 A61B5/402 

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. P_I=(0.04±0.008)H; P_II=(0.18±0.01)H; P_III=(0.15±0.05)H; Q_I=(0.15±0.03)H; Q_II=(0)H; Q_III=(0)H;R_I=(0.15±0.02)H; R_II=(0.33±0.05)H; R_III=(0.35±0.05)H; S_I=(0.18±0.04)H; S_II=(1.40±0.08)H; S_III=(1.43±0.07)H; T_I=(0.075±0.013)H; T_II=(0.52±0.05)H; T_III=(0.51±0.05)H, where H is the amplitude corresponding to control distortion at voltage of 1 mV; P_I, P_III, Q_I, Q_II, R_I, R_II, S_I; S_II, S_III, T_I, T_II, T_III 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.
