Abstract :
A versatile PC-based stimulator has been developed for experimental cardiac electrophysiological investigations. The stimulator is based upon generator units which can be activated in any desired sequence. Each unit includes a trigger controlling the synchronisation conditions, a core determining the pulse characteristics and a sequencer controlling the interconnections between generators. The stimulator allows uninterrupted control over the pulse sequence during the entire experimental time, regardless of the number and nature of protocols. Pulse sequences are automatically generated but are continuously accessible for immediate on-line dynamic adjustments. The stimulator can also operate in a beat to beat sensing and pacing mode. The stimulator generates a broad range of protocols without software modification
