A method of mapping electrophysiological information, including receiving imaging information for a tissue region; receiving a monophasic action potential signal from the tissue region; assigning a value corresponding to a depolarization segment of the monophasic action potential signal; receiving location information associated with the monophasic action potential signal; and generating an image based on the imaging information, the assigned value, and the location information.

Electrophysiological signal processing and utilization

A system and method for controlling the inflation, ablation, and deflation of a balloon catheter. The system includes a balloon catheter, a console, a pressurized gas or liquid inflation source, and an umbilical system to deliver pressurized coolant to the balloon catheter. The system may include controller that monitors the amount of pressure and volume within the balloon catheter. During inflation, the pressure and/or volume of fluid within the balloon is maintained at a target amount in order to provide sufficient mechanized pressure against the desired target region. The system limits the inflation pressure such that a safe quantity of gas would be released should a leak occur. If the amount falls below a certain threshold level, gas or fluid egress is presumed and the inflation process is halted.
