Monitoring Spike Potential and Abrupt Impedance Rise with Concomitant Temperature/Contact Force Change for Timely Detection of the Occurrence of "Silent" or "Nonaudible" Steam Pop.

In conclusion, simultaneously recorded spike potentials and abrupt impedance rise with concomitant temperature and/or CF change could be a feasible method for the timely detection of the occurrence of audible, "silent," or "nonaudible" SP events, particularly in regions where the risk of perforation may be of concern.
