Abstract:
1. A method for detecting patient susceptibility to arrhythmias comprising the steps of: providing means for injecting low level electromagnetic energy stimulations into a patient's body suitable to alter at least one cardiac signal to allow a comparison of acquired distinguishable signal differences with at least one other cardiac signal which has not been affected by said injected energy; connecting a lead system for both sensing the cardiac signals and delivering the injected energy to said means for injecting low level electromagnetic energy into the patient's body, said lead system, comprising a plurality of energy sensing and energy delivery leads and a plurality of energy sensing and energy delivery electrodes; utilizing sensing improvement means for improving the quality of the sensed electromagnetic energy during the stimulation and acquisition process; and evaluating the sensed signal for one or more arrhythmia predictive factors by evaluating variability over multiple QRST complexes by evaluating the relative timing of any combination of P-wave, Q-wave, R-wave, S-wave, or T-wave in a single QRST complex.
