Analysis of one patient with frequent PVCs. Left) Slice volume over time curve of all short axis slices from base to apex. The slice volume curve allows for separation of end-diastolic and end-systolic slice volumes from PVC contractions (red points within the green boxes) from non-ectopic end-diastolic volume (black points within green boxes). Green boxes illustrate end-expiration period of respiration based on visualization of the diaphragm. Right) Volumetric analysis that included all beats (ectopic and non-ectopic), only ectopic beats, and only non-ectopic beats
