• Module to trigger an external stimulator, data acquisition, oscilloscope on ECG R-Wave This module is especially designed to trigger (start) a stimulator or any other device with the R-wave of an ECG signal. The ECG signal has to be measured with the PLUGSYS ECG Amplifier Type 689. The R-wave trigger module is internally connected to the ECG Amplifier and works only together with this amplifier. The R-wave trigger module can be used (e.g., for synchronized stimulation of the heart) by triggering a delay module of a stimulator. It is possible to set the stimulation pulses delayed from the R-wave into the vulnerable phase to produce ventricular fibrillations. The trigger output of this module must be connected to the trigger input of a stimulator with a BNC cable.
