摘要
Various embodiments are described herein for a system and a method for identifying the arrhythmogenic circuit of a patient or subject. In one embodiment, the method comprises obtaining data for electrograms recorded at various locations of the heart while programmed ventricular pacing with extra stimuli was performed, obtaining decrement values for at least two different locations of the heart using the recorded electrograms, generating at least a portion of a decrement map using the decrement values, and identifying the arrhythmogenic circuit based on electrograms having significant decremental properties.
