Temporal relationships between velocity, strain rate ventricular curves, and transmitral flow patterns in pulsed-wave Doppler. The upper panel shows the strain rate (yellow) and velocity (blue) ventricular curves. The lower panel shows the spectral Doppler of transmitral flow. The E wave happens before the early diastolic peak velocity and strain rate of the left ventricle. The mid-diastolic events occur simultaneously. SR-E: peak early diastolic strain rate; SR-L: peak mid-diastolic strain rate; SR-A: peak late diastolic strain rate; G–E’: global early diastolic ventricular velocity using STI; G–L’: global mid-diastolic ventricular velocity using STI; G–A’: global late diastolic ventricular velocity using STI; E wave: early diastolic transmitral flow velocity; L wave: mid-diastolic transmitral flow velocity; A wave: late transmitral flow velocity.
