ELECTROCARDIOGRAPHIC METHOD IN DIAGNOSIS OF MYOCARDITIS IN DOG(LOW VOLTAGE IN THE I-ST STANDARD LEAD)

Violeta Alexandrova

Резюме: Electrocardiographic are studied 59 dogs with changes in the electrocardiogram (ECG), guiding us clinically to changes in the contractile myocardium. The animals are divided into two groups, depending on the voltage (amplitude) of the R wave in different ECG leads, 25 of which are low-amplitude R waves only in the I-st standard lead and 34 cases with low voltage in the same wave recorded in all leads. Calculated and presented are the values for the amplitude and duration of all elements of ECG of the first group dogs as well as the systolic index and electrical axis of the heart in the same animals. Besides the main electrocardiographic sign - low R wave amplitude in the I-st standard lead, in some ECG are met and other related changes that may be in connection with diseases of the pericardial sac of the heart and cases of cardiomyopathies.
