Background
Presence of fragmented QRS (fQRS) complex in a 12-lead electrocardiogram (ECG) has been shown to represent alternation of myocardial activation owing to myocardial scar. The aim of this study was to investigate whether presence of fQRS complex predicts in-hospital and long-term mortality in patients with acute pulmonary embolism (APE).
Methods
This study included 186 consecutive patients with APE. Computed tomography pulmonary angiography (CTPA) was used to diagnose APE. ECG was obtained immediately after admission.
