R-R interval data is presented in a format that includes relevant near field and far field ECG data. The near field view provides a “pinpoint” classical view at classical recording speed. The far field view that provides an “intermediate” lower resolution, pre- and post-event view. Both ECG data views are temporally keyed to the extended duration R-R interval data that is scaled non-linearly to maximize the visual differentiation for frequently-occurring heart rate ranges. All three views are presented simultaneously. The durations of the pinpoint view, the intermediate view, and the R-R interval plot are flexible and adjustable. Diagnostically relevant cardiac events can be identified and located to allow pre- and post-event heart rhythm data. The pinpoint “snapshot” and intermediate views of ECG data with the extended term R-R interval data comparatively depicts heart rate context and patterns of behavior prior to and after a clinically meaningful arrhythmia or patient concern.
