Fragmentation of QRS (fQRS) complex is an easily evaluated non-invasive
electrocardiographic parameter. Fragmentation of narrow QRS is defined as presence of an …

Fragmented QRS (fQRS) is a convenient marker of myocardial scar evaluated by 12-lead
electrocardiogram (ECG) recording. fQRS is defined as additional spikes within the QRS …

QRS Fragmentation and QTc in Hypertrophic Cardiomyopathy Background QRS
fragmentation (fQRS) and prolonged QTc interval on surface ECG are prognostic in various …

BACKGROUND: No information is currently available on the prognostic significance of the
number of leads with fragmented QRS (fQRS). The objective of the study was to clarify the …

Chronic inflammatory disorders, including rheumatoid arthritis (RA), are associated with a
twofold increase in the incidence of sudden cardiac death (SCD) compared with the healthy …

Background In light-chain (AL) cardiac amyloidosis, the 12-lead electrocardiogram (ECG)
reflects myocardial amyloid infiltration with low limb voltages, pseudoinfarction patterns, and …

Systemic sclerosis (SSc) is a complex autoimmune connective tissue disease with distinct
pathological hallmarks (ie, inflammation, vasculopathy, fibrosis) that may predominate at …

Background Obesity has been associated with significantly greater risk of sudden cardiac
death (SCD); however, identifying the obese patient at highest risk remains a challenge. We …

Abnormalities in impulse generation and transmission are among the first signs of cardiac
remodeling in cardiomyopathies. Accordingly, 12-lead electrocardiogram (ECG) of patients …

This article summarizes the main electrocardiogram (ECG) findings in dilated
cardiomyopathy (DCM) patients. Recent reports are described in the great 'pot'of DCM …
