SIMPLE PROCESSING METHOD FOR DISPLAYING RANDOM REENTRITED EXCITATION PROPAGATION AS HIGH-RESOLUTION ANIMATION IMAGE FROM SIMULTANEOUS RECORDING OF LOCAL POTENTIAL OF CARDIAC SURFACE BY SMALL NUMBER OF ELECTRODES

摘要

PROBLEM TO BE SOLVED: To provide a simple processing method capable of displaying random reentried excitation propagation high resolution as animation images from simultaneous recording of the local potential of the endocardium by basket catheters of a small number of electrodes by using personal computers.;SOLUTION: The time interpolation of an excitement period and inter- electrode space interpolation are simultaneously performed in the simultaneous recording of the local potential of the cardiac surface by the small number of the electrodes, by which myocardial excitation systems are displayed as the animation images. An index w(t) reflecting the weight of excitation with time is used for the space interpolation without using the time, by which the space propagation is made correspondent to the randomly enterable excitation propagation. A simple algorithm which may be processable by a personal computer is formed.;COPYRIGHT: (C)2001,JPO
