Figure 7

PW Doppler across mitral inflow is shown during hyperpneac phase (A and B) and during hypopnea (C and D). Green graph in each panel is the respirogram. Note mitral inflow velocity decrease during each inspiration (white arrows, A and B) and increase during each expiration. This exaggerated respiratory change is decreased at the onset of hypopnea in C and abolished during hypopnea in D.
