Fragmented QRS complex: a novel marker of cardiovascular disease.
QRS complex fragmentation, defined as changes in QRS morphology with different RSR' patterns: additional R waves, notched S wave, or > 1R' wave, has recently been linked with various cardiac conditions and even been postulated to be predictive of outcomes in certain pathologies. The current article aims to consolidate the available information about this morphological ECG abnormality and its predictive value.
