MRI-SAFE CARDIAC STIMULATION DEVICE

摘要

An MRI-safe cardiac stimulation device includes a voltage discharge unit adapted to generate voltage pulses, a pair of implantable electrodes connected to deliver voltage pulses from the voltage discharge unit to implanted cardiac tissue, and an electrode isolation system S adapted to electrically isolate the electrodes from the voltage discharge unit during time intervals between the voltage pulses, the electrode isolation system being responsive to the voltage pulses to connect the voltage discharge unit to the electrodes during the voltage pulses.
