Abstract :

Background:Fragmented QRS (fQRS),with an R‘ or notching in the QRS are novel electrocardiographic signals, reflecting altered ventricular conduction delays around myocardial scar.Methods:A prospective observational study done on 100 ACS patients(50 fQRS and without fQRS),March 2014 to October 2015. The patients were followed up for 6 months and EF,Cardiac events were noted.Results:Mean age of presentation was insignificant between two groups.(p=0.8). M:F ratio is 3.2:1, 2.3:1 respectively.Most common risk factors were hypertension,smoking. Most common ACS is STEMI, Anterior wall MI, with single vessel involvement seen in half of the patients. Most common vessel involvement is LAD followed by LCX. Mean EF was 44.35±8.3 at admission, with insignificant increase at 6 months.No relation of fQRS noted with stent thrombosis, hospitalization due to heart failure or mortality.Total number of events were more in patients with fragmented QRS (11vs4, ?2=0.02).Conclusions:The fQRS was not related to age, sex, hypertension, diabetes, smoking, ACS type, vessel involved, but associated with increased events and mortality
