Cardiac stimulator for the study of refractory period control using current pulses of programmable duration and shape

Abstract

A programmable current stimulator has been developed that allows unipolar current pulses of complex shape, long duration and high current to be generated. The stimulator conforms to the safety requirements for devices connected directly to the heart. It incorporates additional safety features to prevent unintended current being delivered, even under fault… (More)
