System and method for facilitating a cardiac rhythm disorder diagnosis with the aid of a digital computer
First Claim
1. A system for facilitating a cardiac rhythm disorder diagnosis with the aid of a digital computer, comprising:
- an electrocardiogram (ECG) monitoring and recording device;
a download station adapted to retrieve cutaneous action potentials of a patient recorded over a set period of time by the ECG monitoring and recording device as ECG data;
a processor and memory within which code for execution by the processor is stored, wherein the processor;
identifies a set of R-wave peaks within the ECG data;
constructs an R-R interval plot, comprising;
determines a difference between recording times of successive pairs of the R-wave peaks in the set and to determine a heart rate associated with each difference;
plots each pair of the R-wave peaks obtained from the ECG monitoring and recording device based on the difference in recording times of that successive pair of the R-wave peaks and the associated heart rate for that successive pair of the R-wave peaks as the R-R interval plot; and
accentuates in the R-R interval plot spatial differences in frequently-occurring ranges of the heart rate and de-emphasizes the spatial differences in ranges of the heart rate where a deviation from the frequently-occurring ranges exists using a non-linear scale for the heart ratea display comprising the R-R interval plot and one or more ECG plots each comprising at least a portion of the ECG data to facilitate diagnosis of a cardiac disorder of the patient based on patterns of the plotted pairs of the R-wave peaks and the associated heart rates in the R-R interval plot and the ECG plots.

Abstract
A system and method for facilitating a cardiac rhythm disorder diagnosis with the aid of a digital computer are provided. Cutaneous action potentials of a patient are recorded as electrocardiogram (ECG) data over a set time period. A set of R-wave peaks is identified within the ECG data and an R-R interval plot is constructed. A difference between recording times of successive pairs of the R-wave peaks in the set is determined. A heart rate associated with each difference is also determined. The pairs of the R-wave peaks and associated heart rate are plotted as the R-R interval plot. A diagnosis of cardiac disorder is facilitated based on patterns of the plotted pairs of the R-wave peaks and the associated heart rates in the R-R interval plot.
