Aline dicrotic notch
WebValve closure is associated with a small backflow of blood into the ventricles and a characteristic notch ( incisura or dicrotic notch) in the aortic and pulmonary artery pressure tracings. After valve closure, the aortic and pulmonary artery pressures rise slightly ( dicrotic wave) following by a slow decline in pressure. WebApr 14, 2024 · Analysis revealed that there exist significant differences in the dicrotic notch portion of the BVP signal for various cardiac conditions . In this study, we extracted a group of twelve morphological features. Table 3 provides complete details of selected morphological features used in this study.
