Assessment of cardiopulmonary function and main pulmonary velocities. Top panel indicates resting cardiopulmonary function as assessed with CPET and values measured occur at peak exercise for VO₂, VE/VCO₂ and PETCO₂. Lower panel depicts resting and peak average and peak pulmonary velocities as measured through velocity encoding sequence with VENC set points of 100 for rest and 150 with stress. Each line represents an individual patient. Dark red line indicates mean value
