Is it safe to leave a PV catheter implanted when defibrillating the heart?

As per Millar's Instructions for Use (see attached for Mikro-Tip and VentriCath), it is recommended to disconnect the Mikro-Tip catheter from all electronics prior to defibrillation or electrosurgery. 
Note: There may be a slight initial offset with the pressure signal when the catheter is reconnected to the MPVS.
