Abstract
An automatic method of determining local activation time (LAT) in multi-channel cardiac electrogram signals including at least two cardiac channels, one of the cardiac channels being a mapping channel and another cardiac channel being a reference channel, the method comprising: (a) estimating a cycle length CL in the reference channel; (b) determining a mapping-channel fiducial time tin the mapping channel signal; (c) determining a plurality of reference-channel fiducial times t; (d) computing adjusted reference-channel fiducial times tby adding or subtracting multiples of cycle length CL to each time tsuch that each time tis within a time window of length CL surrounding mapping-channel fiducial time t; (e) computing a single final reference-channel fiducial time tfrom the plurality of adjusted reference-channel fiducial times t; and (f) computing the LAT as tminus t.
