Fragmented wide QRS on a 12-lead ECG: a sign of myocardial scar and poor prognosis.
BACKGROUND Fragmented QRS (duration <120 ms) on a 12-lead ECG represents myocardial scar in patients with coronary artery disease. However, the significance of fragmented QRS has not been defined in the presence of a wide QRS (wQRS; duration >or=120 ms). We postulate that fragmented wQRS (f-wQRS) due to bundle branch block, premature ventricular complexes, or paced rhythms (f-pQRS) signify myoc...
متن کاملDiffuse Fragmented QRS as an Index of Extensive Myocardial Scar
A 70-year-old man with history of previous myocardial infarction was referred for cardiac resynchronization therapy (CRT) implantation. Echocardiography showed global wall motion abnormality and non-viable myocardium with ejection fraction of 15% and large apical aneurysm. Electrocardiography (ECG) revealed sinus rhythm with wide QRS (200 ms). Of note is the finding of marked fragmentation of Q...
متن کاملDiagnostic value of fragmented QRS complex in myocardial scar detection: systematic review and meta-analysis of the literature.
BACKGROUND AND AIM The present study aimed to investigate the diagnostic value of fragmented QRS complex (fQRS) on 12-lead electrocardiogram (ECG) for myocardial scar detection, and presented the results in a systematic review and meta-analysis format. METHODS Medline, SCOPUS, and ISI Web of Knowledge were searched electronically with "Fragmented QRS" or "fQRS" as key words. All related studi...
متن کاملComparison between fragmented QRS and Q waves in myocardial scar detection using myocardial perfusion single photon emission computed tomography.
BACKGROUND Accurate diagnosis of myocardial infarction (MI) is of paramount importance in patient management, which necessitates the development of efficient and accurate diagnostic methods. Q wave is not present in all patients with MI, and its prevalence is declining. Recently, fragmented QRS (fQRS) complex has been introduced as a marker of prior MI. AIM To investigate diagnostic value of ...
متن کاملFragmented QRS and myocardial performance index in nephrotic syndrome
The recent report on “Fragmented QRS and myocardial performance index in nephrotic syndrome” published is very interesting (1). Özkan et al. (1) concluded that the “determination of fQRS in patients with nephrotic syndrome (NS) in surface ECG, an easily accessible technique, can be used as a parameter in the prediction of myocardial functions.” In fact, it is already known that “fQRS may be use...
