First Claim
Patent Images
1. A method comprising:
- acquiring, using one or more processors, data recordings of at least one of electrical sensor measurements from an electrical sensor, or motion data from a motion sensor, in contact with the region of interest;
determining, using one or more processors, cycle lengths (CLs) associated with cardiac events in the data recordings;
obtaining a test CL from the data recordings;
generating a count of how many cardiac events have CLs that fall within an upper and a lower threshold of the test CL;
identifying, using one or more processors, a reference cycle length based on the count; and
displaying electrical and/or motion map data using a display based on the reference cycle length.

Abstract
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.
