Value of QRS fragmentation as novel electrocardiogram predictor of reperfusion in acute myocardial infarction patient

Background: The main target of treatment STEMI is to restore coronary blood flow and maintain myocardial perfusion. Several tools including electrocardiographic angiographic parameters are used assess reperfusion. Fragmented QRS associated with increased adverse cardiovascular events, it was proved bea marker ventricular dysfunction poor prognosis in STEMI. Aim the work : To study relation between fragmentations degree reperfusion patients treated either fibrinolytic therapy or primary percutaneous interventions (1ry PCI). Patients methods: 100 subjects admitted first attack were included. Twelve leads ECGs evaluated for morphology, randomized two groups according presence absence fragmentation, F-QRS group included 35 NF-QRS 65 patients. following success reperfusion; ST segment resolution, TIMI score, MBG score cardiac enzymes resolution. Results: resolution significantly higher among t. NFQRS had better scores compared group. lower EF Klipp score. CKmb Complications F-QRS. Conclusion: fragmentation can be a reliable predictor acute PCI thrombolytic therapy.
