The independent relationship between systemic inflammation and fragmented QRS complexes in patients with stable angina pectoris.

Abstract

In our study, we found that fQRS was independently related with increased CRP and QRS duration as well as left ventricular systolic dysfunction. Fragmented QRS, which may come about as an end effect of inflammation at cellular level, can represent increased cardiac risk by different causative mechanisms in patients with stable CAD. In addition, fragmentations on ECG may be useful for identifying patients who should be investigated and treated for their increased inflammatory status and possible chronic infections.
