| A HOCM is an autosomal dominant disorder of muscle tissue caused by defects in the genes encoding contractile proteins | | A HOCM is a hereditary illness. |
| | | On the ECG there are signs of [[hypertrophy|left ventricular hypertrophy]] and [[P wave morphology|left atrial enlargement]]. |
| Features
| |
| dyspnoea, angina, syncope
| |
| sudden death (most commonly due to ventricular arrhythmias), arrhythmias,
| |
| heart failure
| |
| jerky pulse, large 'a' waves, double apex beat
| |
| ejection systolic murmur: increases with Valsalva manoeuvre and decreases on
| |
| squatting
| |
| | |
| Associations
| |
| Friedreich's ataxia
| |
| WPW
| |
| | |
| ECHO
| |
| systolic anterior motion (SAM) of the anterior mitral valve leaflet
| |
| asymmetric hypertrophy (ASH)
| |
| mitral regurgitation
