Fig. 6From: Use of self-gated radial cardiovascular magnetic resonance to detect and classify arrhythmias (atrial fibrillation and premature ventricular contraction)ROC curves of arrhythmia classification algorithm performance for classification of NA and A patients (Image a) (red curve; blue curve is line of identity for comparison) and for classification of AF and PVC patients (Image b). A black arrow shows the performance for the chosen parameter thresholds for VVHR and VVval on the a and b curves, respectivelyBack to article page
