A method and system are provided for analyzing data for a region of interest in connection with cardiac mapping. The method and system acquire data recordings of at least one of electrical sensor measurements from an electrical sensor and motion data from a motion sensor in contact with the region of interest, determine cycle lengths associated with cardiac events in the data recordings and identify a reference cycle length from the cycle lengths determined. The method and system analyze the cycle lengths such that differences in heart rate and cycle length have limited effect on an overall map.
