Abstract
The present invention is directed toward methods for inducing fibrillation in a patient using a controlled current AC signal applied via an implanted ICD. In some embodiments, the AC signal is applied as a series of alternating constant current pulses. Some embodiments make use of a specialized H-bridge circuit for applying the AC signal. A low-side current controlling portion of an ICD's circuitry may make up part of the specialized H-bridge circuit. Further embodiments include devices embodying these methods.
