Splet01. mar. 2016 · PCWP was accepted only when: (1) the pressure contour was distinctly different from that recorded in the pulmonary artery on a pullback determination and both the phasic and mean wedge pressures were lower than that of the pulmonary artery; (2) there was fluoroscopic demonstration of wedge position; and (3) there were two … SpletThe P-wave is a small, positive and smooth wave. It is small because the atria make a relatively small muscle mass. If the rhythm is sinus rhythm (i.e under normal circumstances) the P-wave vector is directed downwards and to the left in the frontal plane and this yields a positive P-wave in lead II ( Figure 2, right-hand side).
