Ans. The key is B. Echo. [2 mainD/D of exertional syncope are Aortic stenosis and hypertrophic
cardiomyopathy. Aortic stenosis – more likely in elderly. And hypertrophic cardiomyopathy – more
likely in young and less likely at this age. Echocardiography will reveal the condition of aortic stenosis in this patient].
