- The classic murmur associated to HCM/HOCM is a systolic, crescendo-decrescendo murmur most audible at the left sternal border. This murmur decreases with squatting and increases with subsequent standing. The ECG shows a deep S waves.
- Mitral Valve Prolapse (MVP) is the most common valvular disease. Produces a late systolic click associated with a high-pitched, late systolic murmur. The systolic click occurs closer to S1 with standing. The ECG is normal.
* HCM: Hypertrophic Cardio Myopathy, HOCM: Hypertrophic Obstructive Cardio Myopathy. MVP: Mitral Valve Prolapse
