2064 Fragmented QRS complexes on 12-lead ECG as a marker of greater myocardial infiltration by cardiac magnetic resonance gadolinium-delayed enhancement images in patients with sarcoidosis

Background In our study we demonstrate that presence of either Qwave and or fQRS complexes on a 12-lead ECG in patients with suspected cardiac involvement of sarcoidosis may indicate the presence of greater infiltrative myocardial disease by cardiac magnetic resonance imaging. Fragmented QRS complexes (fQRS) on 12-lead ECG are a marker of greater myocardial scarring and were observed in some sarcoid patients (pts).
