Can I use a Millar Mikro-Tip Pressure catheter in the ventricle while pacing the heart in a working heart model?

This has never been tested and therefore we can't give any recommendations. 
Please be aware that the Millar Mikro-Tip catheter is a sensitive electronic device. It is advised to disconnect the Mikro-Tip catheter prior to defibrillation or electrosurgery. Also avoid electrostatic discharge to the Mikro-Tip sensor.
