Statistical measure of performance in accurately detecting true field potential complexes in arrhythmogenic and morphology changing signals using cross correlation with CF = 0.98.

CF-Correlation factor, TP-True positive, FP-False positive, TN-True negative, FN-False negative, PPV-Positive predictive value.
Sensitivity, specificity and PPV show consistent results for different datasets of arrhythmogenic and morphology changing signals. Results indicate that the correlation analysis is highly sensitive and specific in detecting field potential complexes. A mean PPV of 96.35% indicates that true field potential complexes are detected with a high degree of accuracy, irrespective of the type of signal being analysed.
