Tanriverdi Z, et al. - This study assessed the prognostic utility of the combined use of QRS distortion and fragmented QRS (fQRS) in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). Findings demonstrated that when used in combination, QRS distortion and fQRS afforded additional prognostic value for early risk stratification in this patient populace.
