Systems and methods for generating a composite signal derived from biopotentials sensed in myocardial tissue are disclosed and described. One such method includes inputting a first set of signals comprising biopotentials sensed at a first group of tissue sites during a first time interval; inputting a second set of signals comprising biopotentials sensed at a second group of tissue sites during a second time interval sequentially after the first time interval, wherein at least one of the biopotentials sensed as part of the first set of signals is not sensed as part of the second set of signals, and at least one of the biopotentials sensed as part of the second set of signals is not sensed as part of the first set of signals; and time aligning the first and second sets of signals using biopotentials sensed at the same site as part of both the first and second sets of signals, thereby generating the composite signal arranged for analysis as if all biopotentials were sensed during a common time interval, whereby the composite signal provides a diagnostic indicator.
