Aims Fragmented QRS complex with visible notching on standard 12-lead
electrocardiogram (ECG) is understood to represent depolarization abnormalities and to …

Various noninvasive tests for risk stratification of sudden cardiac death (SCD) were studied,
mostly in the context of structural heart disease such as coronary artery disease (CAD) …

Background Fragmented QRS (fQRS) morphology as a surrogate marker of the possible
presence of myocardial scarring has been shown to confer a higher risk in patients with …

Background—Fragmented QRS (fQRS) has been shown to predict cardiac events in select
patient populations. Whether fQRS improves patient selection for primary prevention …

Background: Increased QRS fragmentation in visual inspection of 12‐lead ECG has shown
association with cardiac events in postmyocardial infarction (MI) patients. We investigated …

Abstract Background Fragmented QRS (fQRS) on a 12-lead ECG has been linked with
adverse outcome. However, the visual scoring of ECGs is prone to inter-and intra-observer …

Background: Several studies have showed that fragmented QRS complexes (f‐QRS, defined
as different RSR′ patterns) on a routine 12‐lead electrocardiogram were associated with …

Abstract Background Fragmented QRS (fQRS) on 12-lead electrocardiogram (ECG) is
associated with scarred myocardium and adverse outcome. However, the data on gender …

Abstract Background Narrow fragmented QRS (fQRS) has recently been recognized as a
significant predictor of prognosis in various cardiovascular diseases. Hypothesis We …

Objective: It has been shown that the presence of fragmented QRS (fQRS) is associated with
poor prognosis in many cardiovascular diseases and in patients with hypertrophic …
