Abstract: Provided herein are systems for modeling a patients cardiac electrical activity data, including at least one diagnostic catheter for insertion into the heart of the patient and a processing unit. The at least one diagnostic catheter includes at least one recording element to record patient data over multiple cardiac cycles. The patient data includes biopotential data and localization data of the at least one recording element. The processing unit includes a clustering routine that: receives the recorded patient data; segments the recorded patient data by cardiac cycle to produce segmented patient data; groups the segments based on one or more characteristics of the segments to produce segmented data groups; and combines the segmented patient data within each segmented data group to produce one or more composite recordings. The systems create one or more models of cardiac electrical activity of the patient based on the one or more composite recordings.

Abstract: Methods of generating a graphical representation of cardiac information on a display screen are provided. The method comprises: electronically creating or acquiring an anatomical model of the heart including multiple cardiac locations; electronically determining a data set of source information corresponding to cardiac activity at the multiple cardiac locations; electronically rendering the data set of source information in relation to the multiple cardiac locations on the display screen. Systems and devices for providing a graphical representation of cardiac information are also provided.
