Utility of Circadian Variability Patterns in Differentiating Origins of Premature Ventricular Complexes

Figure 6

Scatter plot of the diurnal/nocturnal PVC burden ratio in the prospective cohort consisting of ASV and LVOT PVCs. Using a 0.92 cutoff successfully predicted PVC origin in 16/18 cases in a prospective cohort. ASV, aortic sinus of Valsalva; LVOT, left ventricular outflow tract; PVC, premature ventricular complexes.
