All are true regarding hyperophic cardiomyopathy except-
Ref :Harrison's 19th E pg 1568 Digoxin increases the contractility of hea. As contractility increases there is higher chance of obstruction, as the hyperophied septum comes in proximity with the anterior leaflet of the mitral Valve.
Digoxin is helpful
Irregular thickness of septa
Dynamic obstruction
Double apical impulse
