Analysis of spatial and temporal evolution of regularity maps during ventricular fibrillation
The analysis of cardiac mapping allows investigating the structure of ventricular fibrillation (VF). This work analyzes regions of interest (ROI) on cardiac maps obtained from the regularity analysis of VF records, providing information about signal regularity at each time instant and its spatial distribution. Cardiac registers were obtained using a 240- electrodes matrix located on left ventricle of isolated rabbit heart. A Langendorff system was used to maintain the heart perfusion. VF was induced by increased frequencies. Two groups of records were considered: control (G1: without physical training, N=10), and trained (G2, N=9). Records were processed in consecutive 4-second segments. Re…
Modifications on regularity and spectrum of ventricular fibrillation signal induced by physical training
The objective of this work is to study the modifications on cardiac response during ventricular fibrillation (VF) induced by physical training. The analysis was performed in the frequency domain of VF, and the regularity of the signal was also considered. Two sets of records were acquired: control (G1: without physical training, N=10), and trained (G2, N=9). Cardiac registers were obtained using a 240-electrodes matrix located on left ventricle of isolated rabbit heart. A Langendorff system was used to maintain the heart perfusion. VF was induced by increased frequencies. To analyze the time course of VF, records were processed in 4-second segments. For every segment and channel, Welch peri…
Relación entre el espectro y la regularidad en la señal de fibrilación ventricular modificada por el ejercicio físico
El presente trabajo estudia las modificaciones intrínsecas que el ejercicio físico produce en la respuesta cardíaca durante la FV. Se han calculado dos parámetros relacionados con el espectro de la señal (FD: frecuencia dominante, y EN: energía normalizada), y otro relacionado con la regularidad de las OAL (IR: índice de regularidad), Se ha realizado un análisis de correlación entre los tres parámetros para valorar su grado de complementariedad. Se consideraron dos grupos de conejos: control (G1: sin entrenamiento, N=10) y entrenados (G2, N=9). Se utilizó un electrodo matricial de 240 canales localizado en ventrículo izquierdo de corazón aislado de conejo perfundido mediante un sistema de L…
Análisis de regularidad en fibrilación ventricular: aplicación a registros de mapeado cardíaco
Las técnicas utilizadas en el análisis de la señal de fibrilación ventricular (FV), obtenida mediante sistemas de mapeado utilizando matrices de electrodos, extraen información del proceso a partir de parámetros calculados principalmente en el dominio del tiempo o de la frecuencia. El presente trabajo plantea la aplicación del índice de regularidad (IR), propuesto inicialmente para caracterizar la fibrilación auricular humana, a la señal de FV en un modelo experimental de corazón animal. Los resultados obtenidos muestran que el IR permite extraer información de los mapas de FV no disponible de forma directa cuando se estudian mediante los métodos clásicos en el tiempo o la frecuencia, cuant…
Analysis of the influence of parasympathetic postganglionic neurons on cardiac response in Ventricular Fibrillation
Physical training modifies the sympathetic-vagal balance of autonomic nervous system. Previous studies have shown that such training also produces intrinsic modifications of cardiac electrophysiological properties in isolated heart during Ventricular Fibrillation (VF). Ten NZW trained rabbits were studied to test if the modifications are related to the activity of postganglionic parasympathetic neurons. Two records per subject were acquired during VF: before (G1) and after (G2) the infusion of atropine to inhibit the activity of neurons. Mapping records were obtained using a 240-channel electrode array located in the left ventricle of isolated heart (perfused by Langendorff system). VF was …
