DEVICE AND METHOD FOR DIAGNOSING CARDIAC ARRHYTHMIA USING BODY SURFACE POTENTIAL MAPPING

摘要

The present invention relates to a method and device for predicting cardiac arrhythmia using a body surface cumulative potential, which can diagnose and predict cardiac arrhythmia at the beginning. More specifically, the method for predicting cardiac arrhythmia, comprises: a step of amplifying a signal outputted from an electrode mesh where n (n is a natural number) electrodes are arranged in a two-dimensional form to be outputted as a plurality of output potentials; a step of selecting any one among the output potentials as a reference potential to set differences between the reference potential and each of the output potential as active potentials per electrode; a step of defining cumulative potentials of the active potentials per electrode during a basic cycle length as AP_(1cycle) = ∫^T_0 mVdt (dt = sampling cycle) to calculate the cumulative potentials; and a step of defining an average potential as AP_i = AP_(1cycle)/sampling rate(Hz) (i = an electrode number, AP_(1cycle) = a cumulative potential of a corresponding electrode) to calculate the average potential.
