Abstract

Pressure-volume (PV) loops are a modality used to depict the relationship between pressure and volume in the ventricle.1 They are used to represent ventricular performance during a cardiac cycle. A loop is drawn for a single cardiac cycle that is divided into four primary phases. The four phases are ventricular filling (diastole), isovolumetric contraction (systole), ejection (systole), and isovolumetric relaxation (diastole).
