- Title:
- 12 Lead ECG: Hypertrophic cardiomyopathy (HCM)
- Description:
- This ECG suggests left ventricular (LVH) and septal hypertrophy characteristic of hypertrophic cardiomyopathy (HCM).
Left ventricular hypertrophy (LVH) is characterized by enlarged R waves in left-sided ECG leads (I, aVL and V4-6) and enlarged S waves in right-sided leads (III, aVR, V1-V3).
Asymmetrical septal hypertrophy is characterized by dagger-like (narrow and deep) Q waves in inferior (II, III, aVF) and lateral leads (I, aVL, V5, V6).
Septal hypertrophy is characterized by large Q waves in the septal leads (V1-V3)

- Title:
- 12 Lead ECG: Hypertrophic cardiomyopathy (HCM)
- Description:
- Hypertrophic cardiomyopathy with abnormal ST segments, deeply flipped T waves, tall R apical waves, deep Q waves. "Strain pattern" can be observed in the precordial leads.
Common findings on an EKG for patients tall R waves, deep Q waves, inverted T waves, ST segment abnormalities and 'strain pattern' in the chest leads. The deep Q waves indicate septal hypertrophy and similarly deeply inverted T waves indicate apical hypertrophy.
