摘要:
An apparatus, comprising: a probe (14) that has a plurality of electrodes (32; 33) and is adapted for insertion into the heart of a living subject; and a processor (22), which is configured to receive an electrical signal from the electrodes and to perform the steps of: recording electrograms of the electrodes at respective locations in the heart; determine the bipolar windows in the electrograms; note the local activation times within the bipolar windows; determine from the readings of a set of electrodes that there is a blocking point in a region of the set of electrodes; reset the local activation time notations noted in response to the blocking point; determine the revised windows that include the respective local activation times; identify primary slopes denoting activation at the respective locations, and secondary slopes denoting remote effects, on electrograms; determine if the electrodes are in contact with the heart; determine whether the primary and secondary slopes are coupled to each other; and determine the propagation blocking lines in the heart when the primary slope and the secondary slope are coupled to each other and the electrodes are in contact with the heart.Un aparato, que comprende: una sonda (14) que tiene una pluralidad de electrodos (32; 33) y está adaptada para su inserción en el corazón de un sujeto vivo; y un procesador (22), que está configurado para recibir una señal eléctrica de los electrodos y para realizar los pasos de: registrar electrogramas de los electrodos en localizaciones respectivas en el corazón; determinar las de ventanas bipolares en los electrogramas; anotar los tiempos de activación local dentro de las ventanas bipolares; determinar a partir de las lecturas de un conjunto de electrodos que existe un punto de bloqueo en una región del conjunto de electrodos; reposicionar las anotaciones de tiempo de activación local anotadas en respuesta al punto de bloqueo; determinar las ventanas revisadas que incluyen los tiempos de
