Figure 2

A typical representation of a left atrial pressure–volume loop. The arrows indicate the time course. Mitral valve opening and closure are identified by dots. “A” is the A loop representing the active phase of the atrial cycle and “V” is the V loop associated to the passive phase of the atrial cycle. The blue segment is the reservoir phase; the orange segment is the conduit phase; the grey segment is the pumping phase. The inverse slope of the dashed line represents the atrial compliance. LA left atrium/atrial, MV mitral valve.
