Résumé
This study aimed to analyze the prognostic value of fragmented wide QRS (f WQRS) in patients with acute ST-segment elevation myocardial infarction (STEMI). Eighty-five STEMI patients treated in our hospital from September, 2016 to August, 2017 were selected as objects of study. The patients were divided into Group A (GA, n=15), Group B (GB, n=12), Group C (GC, n=12), Group D (GD, n=16), Group E (GE, n=11) and Group F (GF, n=19) according to results of the electrocardiogram (ECG). The six groups were detected and analyzed with respect to coronary artery lesions, invasion site, cardiac parameters, myocardial injure markers, Killip grading, and prognosis. GA and GB had right coronary artery occlusion; GC mainly had right coronary artery occlusion and circumflex artery occlusion, and GD mainly had right coronary artery occlusion. The invasion site of GE was mainly in the proximal (middle) segment of anterior descending branch and that of GF in the (middle) distal segment of the anterior descending branch. Monitoring the phenomenon of QRS in ECG is an effective method to evaluate the disease condition and prognosis of STEMI patients. Therefore, this method shall be emphasized in clinical practice.
