36. Choice B is the correct answer. Hypertrophic cardiomyopathy has a normal or small ventricular size and a thickened inter ventricular septum. It causes outflow obstruction which can cause diastolic problems and chest pain and shortness of breath with exertion. It does produce a systolic murmur but can produce a S3 and S4 gallop because of the ventricle becoming stiff. This is treated ideally with calcium channel blockers. These patient can have life threatening arrhythmias.
