What's The Predictive Value of Fragmented QRS in Mortality for Chronic phase of Pulmonary Thromboembolism?

Presence of fragmented QRS (F(QRS)) complex in a 12-lead electrocardiogram (ECG) has been shown to be the defect of the intramyocardial conduction. F(QRS) on ECG is related to high mortality rate in patients with acute coronary syndrome and pulmonary thromboembolism. There is no information about the mortality of chronic pulmonary embolism among patients with F(QRS). The aim of this study is to evaluate the patients who has already diagnosed with  pulmonary thromboembolism (PTE) associated with fragmented QRS on ECG and to decide the effects of all-cause mortality in long term follow-up.
