| Abstract (English): | The electrocardiogram is a valuable tool in the study of the cardiac electrical activity, and localization of the integral electric vector average (IEV) of the complex QRS is an important aspect for the diagnosis of cardiovascular alterations. The aim of the present work was to design an algorithm allowing the automated determination of the position of the average EIV of the complex QRS in equine. Twenty seven electrocardiographic registers of equines were collected and the net QRS voltages measured in the derivations V1c, V5c and V6. The calculations were made by means of a computer and manually after taken the pseudocode to the Java language through the environment NetBeans IDE 8.0. The results showed that there were no differences between the numerical values when the data were processed by the two methods used. It is concluded that the algorithm presented is reliable regarding the steps to follow for determining the position of the average IEV of the complex QRS because in comparing the results obtained by both the computer and manually, all the values coincided completely in all the cases. Thus, if the length of the waves recorded in the monopolar derivations V1c, V5c and V6 is measured, it is possible to calculate the spatial orientation of the IEV of any of the electrocardiographic waves. That corresponding to the complex QRS is located in the second octant, in cephalic direction. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): | El electrocardiograma es una herramienta valiosa en el estudio de la actividad eléctrica cardíaca y la ubicación del vector eléctrico integral (VEI) medio del complejo QRS y es un aspecto importante para el diagnóstico de alteraciones cardiovasculares. El objetivo del presente trabajo fue diseñar un algoritmo que permite la determinación automatizada de la posición del VEI medio del complejo QRS en equinos. Se recolectaron 27 registros electrocardiográficos de equinos y se midieron los voltajes netos del QRS en las derivaciones V1c, V5c y V6. Los cálculos se realizaron por medio de la computadora y de forma manual después de haber llevado el pseudocódigo al lenguaje Java, a través del entorno NetBeans IDE 8.0. Los resultados mostraron que no hay diferencias entre los valores numéricos al efectuar el procesamiento de datos por los dos métodos utilizados. Se concluye que el algoritmo presentado es confiable en cuanto a los pasos a seguir para la determinación de la posición del VEI medio del complejo QRS, ya que al comparar los resultados obtenidos a través del cálculo por medio de la computadora y de forma manual, se comprueba que los valores coinciden totalmente en todos los casos. De esta forma, si se mide la amplitud de las ondas registradas en las derivaciones monopolares V1c, V5c y V6 se puede calcular la orientación espacial del VEI de cualquiera de las ondas electrocardiográficas. La correspondiente al complejo QRS se ubica en el segundo octante, en dirección cefálica. [ABSTRACT FROM AUTHOR] |
