Should not change LVOTO management; hypothesis-generating for hypertrophy-related septal activation delays.
In patients with hypertrophic obstructive cardiomyopathy, total septal activation time is prolonged due to hypertrophy despite normal conduction velocity, and there is a delay in subendocardial activation of the anterior paraseptal left ventricular wall.
Dam et al. (1972) studied this question.
