Group‐averaged traces for the simultaneous assessment of cardiovascular parameters aligning with the carotid artery longitudinal motion (CALM) pattern. Panel A: Alignment of CALM with basal septal displacement (positive deflections indicating movement towards the apex), basal septal velocity, and carotid blood velocity. Panel B: Alignment of CALM with apical rotation (positive deflections indicating counter‐clockwise rotation), rotation velocity and carotid blood velocity. Panel C: Alignment of CALM with basal rotation (positive deflections indicating counter‐clockwise rotation), rotation velocity and carotid blood velocity. Standard deviation lines have been removed for clarity. ES, end‐systole.
