PLUGSYS R-Wave Trigger Module (RWT)
Triggers (starts) a stimulator or any other device with the R-wave of an ECG signal. Requires ECGA module.
The R-Wave Trigger Module (RWT) is especially designed to trigger (start) a stimulator or any other device with the R-wave of an ECG signal.
The ECG signal is measured with the PLUGSYS ECG Amplifier Module (ECGA) . 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.
