Abstract:
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; applying the electrodes, connected to said lead system, to the patient's body; optimizing the electrodes to induce Wedensky phenomena; 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 selected from a group consisting of: heart rate variability, QRST timing changes, ST segment elevation and T wave changes.
