Abstract:
1. Defibrillation apparatus, comprising: a defibrillation energy source; a plurality of first electrodes adapted for the delivery of defibrillating energy generated by said source to a subject; a plurality of second electrodes adapted for obtaining electrocardiographic and impedance signals from said subject, at least two of said plurality of second electrodes being disposed in an optimized spacing relative to one another; a stimulation current source operatively coupled to at least one of said plurality of second electrodes; first processing apparatus adapted to process said electrocardiographic signals to generate first output, said processing of said electrocardiographic signals comprising at least time-scale domain processing; second processing apparatus adapted to process said impedance signals and said first output to generate second output, said processing of said impedance signals and first output comprising at least B and X point detection; and fuzzy logic decision apparatus adapted to receive said second output and determine whether said delivery of defibrillating energy is appropriate based at least in part thereon.
