Features of Hyperophic Cardiomyopathy include all of the following except:

Answer is B (Murmur radiating to neck) Hypetrophic cardiomyopathy is characterized by a harsh systolic diamond shaped (crescendo-decrescendo) murmur best heard at lower left sternal border as well as at apex. Murmur does not radiate to the neck. Other features mentioned are consistent with the diomocis Valsalva maneuver and sudden standing decrease the volume of blood in LV and increase the obstruction by allowing better opposition between the hyperophied septum of the mitral valve leaflet. Thus these will also increase the intensity of the murmur
