Computer graphic on right illustrates the steps necessary to analyze PVZ using the CompositePVZ © software. This includes measuring pulmonary artery (PA) diameter, tracing of PA pressure waveforms, pulsed-wave Doppler waveforms, and corresponding electrocardiogram signals. It also illustrates the user interface encountered when selecting beats (bottom left), and impedance spectra at desired timepoints (bottom right).
