Hypertrophic cardiomyopathy

Hypertrophic Cardiomyopathy (HCM) is an inherited disorder associated with sudden death in young athletes. ECG features include tall QRS complexes, dagger Q waves and wide P waves. In the uncommon Apical HCM there is also giant T wave inversion. Arrhythmias such as AF or SVTs are common and there is a risk of VT. It is also associated with Wolff Parkinson White syndrome.

HCM has also been known as Hypertrophic obstructive cardiomyopathy (HOCM) or idiopathic hypertrophic subaortic stenosis (IHSS).
