Electrocardiographic QRS Fragmentation as a Marker for Myocardial Fibrosis in Hypertrophic Cardiomyopathy

Myocardial fibrosis in patients with hypertrophic cardiomyopathy (HCM) usually shows a patchy distribution, which may not be detected by pathological Q waves on 12‐lead ECGs. Fragmented QRS complexes (fQRS) reflect intraventricular conduction delay and can be a marker of myocardial fibrosis. We assessed whether fQRS show better correlation with myocardial fibrosis than pathological Q waves in HCM.
