All are true about hyperophic obstructive cardiomypathy except-: (A) Asymmeric hyperophy of septum, (B) Systolic motion of anterior leaflet, (C) Left ventricle outflow obstruction, (D) Beta blockers are not effective
Answer is D. Ref:Harrison&;s 19th E pg 1568. Beta-blockers are the drug of choice for HOCM. Decreasing the contractility of hea prevents the hyperophied septum coming in contact with the anterior leaflet of the mitral Valve. Hence reducing the obstruction.
