Figure 4

Left ventricular (red), aortic root (pink) and left atrial pressure (brown) during two heart cycles. An early diastolic as well as a late positive ventriculo-atrial pressure gradient results in the mitral E and A-waves respectively. A post-ejection aortic pressure incisura is seen corresponding to aortic valve closure followed by a “reflected” wave.
