Abstract

The current article provides a detail review of foreign publications, discussing the opportunities and the benefits of evaluation of the QRS-fragmentation (fQRS) — a new electrocardiographic (ECG) parameter in patients with coronary artery disease (CAD). Diagnostic criteria for narrow and wide QRS-complexes are defined. Main results of the comparative and correlation analysis, evaluating fQRS and electrocardiographic (pathologic Q-waves), echocardiographic (left ventricular ejection fraction), angiographic settings are described. There is a discussion of the prognostic role of fQRS in stable CAD as well as in patients presented with acute myocardial infarction. fQRS is an available ECG-marker of local myocardial fibrosis. It seems to be a useful negative predictor in individuals with CAD, indicating an increased risk of life-threatening ventricular arrhythmias and recurrent cardiac events. The presence of fragmented QRS-complexes is associated with an increased in-hospital and long term (overall as well as cardiovascular) mortality. Routine evaluation of fQRS in standard ECG leads does not require additional resources, and will contribute to an improvement in diagnostics and risk stratification of stable CAD as well as myocardial infarction. Assessment of fQRS can be included in noninvasive diagnostic algorithm concerning CAD.
