Prevalence and Temporal Distribution of Extrasystoles in Septic ICU Patients: The Feasibility of Predicting Fluid Responsiveness Using Extrasystoles

Figure 2

Visualization of extrasystolic coverage in the selected cohort. Solid line is the coverage of all extrasystoles (“supraventricular,” “ventricular,” and “of unknown origin”). Each “plateau” in the curves represents a patient’s extrasystolic coverage. Each curve is sorted from lowest to highest extrasystolic coverage to make the areas under the curves easier to visualize and interpret; that is, the coverage numbers presented in the rightmost column of Figure 3 have been sorted (ranked) and plotted against the rank (1 up to 50). The area under each curve divided by the graph’s entire area therefore corresponds to the estimated mean extrasystolic coverage across the patients (53.3%). If not-analyzable patients (the grey area) are excluded, the mean extrasystolic coverage is 63.5%.
