UTILIZAÇÃO DO ELETROCARDIOGRAMA PARA DETECÇÃO DE ARRITMIAS EM CÃES

Abstract

The electrocardiogram (ECG) is an essential tool for graphically recording the electrical activities of the heart, fundamental in evaluating rhythm and heart rate. It records the average electrical potential generated by the heart during each heartbeat. The ECG is especially indicated for the diagnosis of arrhythmias and abnormalities detected during physical examination, cardiac auscultation, and in situations such as complaints of epilepsy and exercise intolerance. In this study, 28 dogs of different breeds and ages were used for routine cardiac evaluation and as a pre-surgical complementary examination, aiming to better choose the drug to be used. Of the 28 animals analyzed, 78% showed changes in the electrocardiographic tracing. In the electrocardiographic examination, the amplitude of the T wave was evaluated and, in order to verify changes in electrical conductivity, it was observed whether the rhythm of the electrocardiograms was sinus and whether each P wave was followed by a QRS complex. In addition, the amplitude and duration of the P wave in addition the duration of the QRS intervals.
