The prognostic implications of a fragmented QRS pattern in patients diagnosed with heart failure

Objectives: The purpose of this study was to investigate the potential association between presence a fragmented QRS (fQRS) pattern on electrocardiogram (ECG) and prognostic outcomes in patients with heart failure (HF). Methods: In study, 238 left ventricular ejection fraction less than 35% were included. fQRS ECG analyzed all patients. Patients divided into two groups based or absence ECG. primary clinical end points all-cause mortality rehospitalization. Results: Baseline demographic characteristics comparable groups. had higher frequency coronary artery disease atrial fibrillation (72 (76%) vs 90 (62%), (p = 0.023; 27 (29%) 25 (17%), 0.038, respectively). Additionally, rate rehospitalization during 5-year follow-up period compared without fQRS. (30 (32%) / 28 (19%), 0.028; 56 (60%) 50 (35%), p < 0.001, Multivariable logistic regression analysis revealed that independently associated ((p 0.02 Conclusions: results suggest HF is related risk hospitalization. Therefore, may be useful indicator poor prognosis these
