Association of the Zwolle Score with Fragmented QRS Complex: A Combined Prognostic Tool for Primary Angioplasty in ST Elevation Myocardial Infarctions -

Introduction: We aimed to introduce the prognostic value of simultaneously calculated fragmented QRS and Zwolle scores as a new scoring system in primary PCI of the STEMI patients. Method: Two hundred fifty-nine STEMI patients were classified as fragmented QRS complex group (fQRS) and non-fragmented QRS complex group (non-fQRS) according to the fragmentation of QRS complex in electrocardiography. These two groups according to whether Zwolle score ≥3 were also classified as high Zwolle score with fQRS complex, high Zwolle score with the non-fQRS complex, the low Zwolle score with fQRS complex, and low Zwolle score with the non-fQRS complex group. The hospitalization data of the patients were analyzed. Results: In the fQRS group compared with the non-fQRS group, wider QRS (105.2±9.7 vs. 88±7.1, p
