The measure stimulating threshold of neuromuscolar tissues: instrumentation and applications in cardiac stimulation

The measure of the stimulating threshold of neuro-muscolar tissues is currently done refering to voltage or current (1,2). However the tissues are tipically non linear system so taht the simulating threshold is not well defined only on the basis of the voltage or current. Some authors (3,4) have succesfully suggested to measure the stimulating threshold as the energy required to obtain a response.
