RESUMEN

Las extrasístoles ventriculares se han convertido en objeto de tratamiento, especialmente si la carga de arritmia es mayor al 10% de los latidos en un día. Conocer el sitio de origen de las mismas permite optimizar la planeación de las estrategias de tratamiento, especialmente las invasivas. El análisis deductivo del electrocardiograma (ECG) es una forma racional de analizar los vectores de activación y las morfologías de las extrasístoles, gracias a la cual se puede definir de manera bastante precisa el foco de origen de la arritmia. Conocer la posición de las estructuras cardiacas en el tórax y en el propio corazón, así como las relaciones entre ellas, facilita la comprensión de los vectores y morfologías de los complejos en el ECG de doce derivadas y es una información valiosa para completar el panorama clínico del enfermo. En este trabajo se presentan las principales formas de analizar el ECG de las extrasístoles ventriculares a partir de los conceptos clásicos y se incluyen parámetros de diagnóstico para definir su origen.
