Study of Prognostic Significance of Terminal QRS Complex Distortion in Acute ST Elevated Myocardial Infarction (STEMI) At a Tertiary Care Centre

Terminal QRS Complex Distortion in Acute ST Elevated Myocardial Infarction

Abstract

Background: To Study the Prognostic Significance of Distortion of Terminal QRS Complex in Acute ST Elevated Myocardial Infarction (STEMI) at a tertiary care centre. Subjects and Methods: All patients diagnosed with Acute STEMI were screened and divided into two group QRS distortion (Group 1) and without QRS distortion (Group 2) based on admission ECG findings. 2D ECHO findings were noted in view of LVEF & WMSI Index and Comparison of parameters was done. Results: There were more males as compared to females. Mean age among Group I subjects was 54.07 5.38 years and among group II subjects was 52.19 4.92 years.  Amongst the group I subjects the mean time of presentation at Hospital (window period) was 151.58 7.64 minutes while among group II subjects, the mean time of presentation at Hospital (window period) was 184.246.81 minutes. Moderate dysfunction was more in group I while mild dysfunction was more in group II with statistically significant difference as p<0.01. Mean stay at hospital was 10.82 8.93 days. The mean WMSI index comparatively higher in group I (2.98 0.32) as compared to Group II (2.04 0.47). Conclusion: Presence of terminal Q.R.S distortion on E.C.G was linked to L.V.S dysfunction of S.T.E.M.I patients.
