摘要：
Systems and methods for epicardial electrophysiology and other procedures are provided in which conditions at the location of an access needle may be determined according to the detection of different pressure frequencies in separate organs, or different locations, in the body of a subject. Methods may include inserting a needle including a first sensor into a body of a subject, and receiving pressure frequency information from the first sensor. A second sensor may be used to provide cardiac waveform information of the subject, and the pressure frequency information may be segmented based on the cardiac waveform information. Conditions at the current location of the needle may be determined based on an algorithm including the segmented pressure frequency information and the cardiac waveform information.
