The timing diagram model could provide the cardiologist with the ways and means of quantifying interval/segment patterns. This analysis would be more exact than present use of electrocardiograms, which relies on subjective analyses of pathological events and the graph patterns they present. Improving the predictability of pathological events by filtering out overriding ventricular depolarization could identify sequential patterns of the atrial repolarization interval/segment. A healthy heart could provide a standard against which specific syndromes might be compared and contrasted for diagnostic purposes. The clinician would have yet another diagnostic tool which could identify patterns requiring aggressive preventive therapy much earlier in the clinical cycle of the patient with a family history of cardiovascular disease. Results of various treatments prescribed for the broad spectrum of cardiological pathologies could also be evaluated in relation to the manner in which these treatments bring the cardiac cycle into synchrony with normal patterns. This comparison would be accomplished by comparing the sequencing and length of time for specific interval/segment patterns demonstrated before, during, and after the treatment occurs. If successful, the proposed analysis of the ECG would ultimately contribute to more positive outcomes for patients who presently may have a poor prognosis. >
