Method of noninvasively determining a patient's susceptibility to arrhythmia

A device for detection of a patient's susceptibility to arrhythmias, the device comprising:

• means for injecting low level electromagnetic energy stimulations into a patient's body, the stimulations being suitable to alter at least one cardiac signal;
• means for comparing a cardiac signal affected by the injected energy stimulations to at least one other cardiac signal which has not been affected by said injected energy;
• 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 at least one energy sensing and at least one energy delivery lead;
• and
• at least one sensing improvement means, for improving the quality of the sensed electromagnetic energy during the stimulation and acquisition process, the sensing improvement means comprising means for executing an algorithm comprising Wavelet Decomposition analysis of the cardiac signal(s).

A method for assessing cardiac condition comprising the steps of:

• providing means for injecting low level electromagnetic energy stimulations into a patient's body suitable to alter at least two cardiac signals to allow a comparison of acquired distinguishable signal differences between said at least two cardiac signals which are 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 which are selectively functionally connectible at different positions, for delivery of optionally different energies for optionally different durations;
• and
• utilizing sensing improvement means for improving the quality of the sensed electromagnetic energy during the stimulation and acquisition process and comparing differences or similarities to determine cardiac condition.
