Análisis de variabilidad del intervalo QT en la señal electrocardiográfica

Abstract

El electrocardiograma o ECG es una representacion gráfica de las fuerzas eléctricas que trabajan dentro del corazón. durante el ciclo cardíaco de bombeo y llenado, un patrón conocido de pulsos eléctricos cambiantes refleja exactamente la acción del corazón. Estos pulsos pueden ser recogidos a través de eléctrodos pedgados a la superficie del cuerpo. La actividad del corazón representada por ondas características puede así ser evaluada instantáneamente en un monitor o ser impresa sobre un papel milimetrado para su estudio superior. Desde su invento a principios del siglo XX, el ECG ha sido la herramienta más importante del cardiólogo. Resulta imprescindible en el diagnóstico de las arritmias cardíacas, y pueden dar información sobre la presencia de enfermedad coronaria antígua o reciente, y de otros problemas del corazón.
