Figure 3.

(A) A schematic diagram of a left ventricular global flow-volume estimates loop. The flow-volume estimates loop proceeds in a clock wise direction. Minimum and maximum volumes are readily identified as well as maximum systolic and maximum diastolic flow. Isovolumic systolic and diastolic events are also identifiable. Integrals of the flow-volume estimates loop are also shown representing the (B) diastolic, (C) systolic, (D) early diastolic, and (E) early systolic volume changes.
