AB  - INTRODUCTION: We aimed to evaluate the effect of exercise-based cardiac 
      rehabilitation (CR) on the fragmented QRS (fQRS) in patients with ST elevation 
      myocardial infarction (STEMI). METHODS: Ninety-seven patients with STEMI 
      participated CR and 81 patients as a control group were included to the study. 
      The trained patients were grouped according to the presence and persistence of 
      QRS fragmentation on the electrocardiogram (ECG) before and after CR. If the 
      fragmentation was present on the ECG at the beginning of the CR but not on the 
      ECG at the end of CR; the transient group, if the fQRS persists after CR; the 
      persistent fQRS group. ECGs obtained from the control group were grouped 
      according to the presence of a fQRS on ECG. RESULTS: Among the trained patients, 
      45 (46%) did not have a fQRS before CR, whereas 52 (54%) presented a fQRS before 
      CR, which was persistent in 35 patients (the persistent fQRS group) and transient 
      in 17 patients (the transient fQRS group). Among 81 patients included in the 
      control group, fQRS was persistent in 41 patients. Presence of fQRS on the ECG 
      was significantly decreased with CR and it is better in trained group than the 
      control group (P = .034). There were not significant correlations with other 
      characteristics, except hypertension. CONCLUSION: The existence of the fQRS 
      decreases after CR in patients with STEMI especially in hypertensive individuals, 
      which may be related to improved electrical stability in the myocardium as a 
      predictor of increase in survival and decrease in major cardiac events.
