摘要:
A method and system for cryotreatment and mapping of target tissue. The cryotreatment system may include a cryotreatment catheter, a mapping catheter including one or more mapping electrodes, and one or more temperature sensors located on the mapping catheter and/or the cryotreatment catheter. The cryotreatment catheter distal tip may be short enough to allow at least one mapping electrode to be positioned proximate the cryoballoon, for example, within 6 mm or less from the cryoballoon. Energy, such as radiofrequency energy, may be delivered to one or more mapping electrodes when one or more temperature sensors indicate a temperature of approximately 0° C. or below at one or more mapping electrode in order to thaw or prevent the formation of ice on the mapping electrodes when positioned proximate a cryoballoon during a cryotreatment procedure in order to recapture cardiac signals.
