Energy: 3-dimensional pulse volume from multipoint array pressure sensor. Pulse volume can be calculated by integration of pulse amplitude envelope. : amplitude of incisura is affected by amplitude of reflected wave. : time to first peak from baseline correlates with vessel compliance. : duration of left ventricular systole. : left ventricle diastolic phase; T is equivalent to one pulse period. : pulse wave area. : ratio of systolic phase to pulse wave area. : ratio of diastolic phase to pulse wave area. RAI: radial augmentation index, which is calculated as : (ratio of height of the aortic peak to the height of the main peak), related to vessel’s stiffness and aging. /min: mean energy per minute. : ratio of systolic phase to total pulse period. : ratio of systolic phase to diastolic phase. Note: increased duration of systolic phase may indicate increased stroke volume or cardiac loading.
