Table 2. – Association of cardiac magnetic resonance fibrosis identified in late enhancement images (visual detection) and presence of fibrosis suggested by q waves ( ≥0.04 s in duration and ≥25% of R wave size or lack of progression of R wave increase in precordial leads) in electrocardiogram. Chi-Square=0.007.

Fibrosis	CMR absent	CMR present
ECG absent	18	32
ECG present	0	14

CMR: cardiac magnetic resonance; ECG: electrocardiogram.
