Abstract:
1. In an electrophysiology computer system, a processor configured to derive a non-synchronous subcomponent from a first heartbeat signal having a composite waveform which includes a synchronous subcomponent overlapping the non-synchronous subcomponent, by executing the steps of: (a) selecting a synchronous subcomponent of a second heartbeat signal which corresponds to the synchronous subcomponent of the first heartbeat signal; (b) permitting a user to mark a begin point and an end point of the selected synchronous subcomponent; (c) defining a reference template as being a waveform segment between the marked begin and end points of the selected synchronous subcomponent; (d) acquiring the composite waveform of the first heartbeat signal at the signal processing unit from multiple leads; and (e) processing the composite waveform beat so as to derive the non-synchronous subcomponent; wherein the selected synchronous subcomponent is from a single beat.
