Caracterización de componentes fisiológicos electrocardiográficos en felinos clínicamente sanos de la ciudad de Ibagué - Tolima

Resumen

The electrocardiogram is a diagnostic and monitoring method widely used in the clinic of small animals, it is very useful to rule out cardiac and electrolytic pathologies. Few studies have been carried out in felines about the appropriate methodology for taking these récords and their physiological parameters, and the studies that exist are not from this country, so the data may differ from the physiological patterns that are presented in this geographical area. In order to provide physiological electrocardiographic parameters, a population of 30 clinically healthy domestic cats from the city of Ibagué was taken, a clinical examination was performed and an electrocardiographic record was taken in the right decubitus position. All the records were taken in the electrophysiology laboratory of the Cooperative University of Colombia in the Lab Chart pro version 8 1. 12.24 software. In these records, the amplitude and duration of the P wave, PR segment, QRS complex, ST segment and T wave were measured. The variability of heart rate in the time and frequency domain was also determined. Using the SPSS IBM Statistics Version 25 statistical package, the electrocardiographic parameters were described with respect to 3 age groups (0 to 1 year, between 1 and 6 years and over 6 years) of domestic cats. It was found that the average heart rate decreases as age progresses, it occurs the opposite with the average respiratory rate, which turns out to be lower in young animals. Predominance of R morphology was observed in the QRS complex and carp form in the P wave between individuals. Finally, it was possible to find an approximation of the duration, amplitude and morphology of the waves, as well as the duration of segments and intervals; in addition to the heart rate and heart axis range. Veterinary doctors can take these values as a diagnostic reference, to detect possible anomalies in the values that indicate any pathology.
