2307 is a medical device serving for diagnostic purposes. For safety reasons in the conduction of the clinical procedure, the device has been fitted with a specific emergency stimulation function that can be activated from a specific control, and with an high frequency asynchronous stimulator to terminate an a trial tachyarrhythmia, in case of initiation during the procedure.

The diagnostic functions envisaged in the device for detecting the useful parameters for programming permanent heart stimulation are four and these can be identified from the following indications:

*Auto-Sense - (function for measuring the sensing parameters with automatic detection by the electro gram);

*Pace threshold S00 (function for measuring the threshold via asynchronous stimulation);

*Pace threshold SSI (function for measuring the threshold via stimulation on request);

*5V Impedance (function for measuring the impedance of stimulation circuit via asynchronous stimulation)
