Miscellaneous ECG 7
- Normal sinus rhythm
- Hypertrophic obstructive cardiomyopathy (HOCM)
Hypertrophic obstructive cardiomyopathy (HOCM) is a pathologic cardiac condition in which the interventricular septum is abnormally thickened. The classic finding in HOCM is large dagger-like “septal Q waves” in the lateral leads due to the abnormally hypertrophied interventricular septum. The apical variant of hypertrophic cardiomyopathy does not result in septal Q waves as the sepum is normal in thickness in this condiction. The cardiac apex is thickened resulting in diffuse T wave changes throughot the preocordial leads.
