Abstract: A pair of new catheters designed to be deployed as a catheter system to allow a simultaneous acquisition of electrograms from widely dispersed electrodes in the left atrium, right atrium, and coronary sinus. The first catheter is the spiral globe catheter which has the primary shape of a spiral globe and has additional modifications to facilitate safe entry into the left atrium, to orient the primary axis of the spiral globe toward the mitral valve, and to maximize contact of electrodes to multiple areas of the left atrium. The second catheter is the right atrial and coronary sinus catheter (RA-CS catheter) which allows for electrogram acquisition from the length of the coronary sinus and dispersed areas of the right atrium. The catheter system is designed to provide adequate electrode sensor information so that panoramic mapping of the both atria and the coronary sinus may be performed.

Abstract: Described is a system and method for recording and receiving a plurality of electrograms, each electrogram corresponding to a region of a heart, wherein the electrograms are recorded substantially simultaneously. A plurality of fiducial markers are identified on a selected electrogram, wherein each fiducial marker marks a feature of interest in the first electrogram. Multiple segments of each of the plurality of electrograms are aligned with each segment temporally corresponding to each of the fiducial markers on the selected electrogram. The aligned segments of each of the plurality of electrograms are averaged resulting in an average electrogram for each of the plurality of electrograms. Features of interest are identified in each of the plurality of average electrograms and relationships are determined between features of interest in each of the plurality of average electrograms.

Abstract: Described is a method of delivering a pacing pattern to a heart, measuring a response of the heart to the pacing pattern, the measured response including a series of electrograms representing a plurality of heartbeats of the pacing pattern and calculating diagnostic data from the measured response, wherein the diagnostic data includes data in one of a time domain and a frequency domain.
