Actual (reported)This post-marketing evaluation has been designed to consistently investigate the subject's preference when switching from a Medtronic® constant voltage or constant current device to a St Jude Medical Infinity™ or St Jude Medical Brio™ constant current system. As electrodes will not be re-positioned, differences in subject's preference are to be explained by the difference in shape of the delivered pulse or waveform between the two systems.
