Systems and methods for characterizing aspects of an electrocardiogram signal are presented, wherein primary and secondary analysis schemas are utilized to determine the timing of the end of a signal wave, such as a descending Twave, with precision. In one embodiment, the primary analysis schema involves comparing voltage amplitudes within a given sampling window and the secondary analysis schema involves comparing the results of primary analysis for successive sampling windows. The system may comprise a processor or microcontroller embedded into a system such as an electrocardiogram hardware system, personal computer, electrophysiology system, or the like.
