Fragmented QRS and Chagas’ disease

Fragmented QRS and Chagas' disease

Unfortunately, the authors have missed our 2 publications on this topic which have been tested in a larger population of CD patients with an implantable cardioverter-defibrillator (ICD) (FECHA study) [2,3]. We included 98 patients from 14 centers in Latin America, all of them with CD cardiomyopathy and an implantable cardioverter-defibrillator (ICD). The mean follow-up was 33±20 months. Mean LV...

Fragmented QRS Electrocardiogram - The Hidden Talisman?

Fragmented QRS: What Is The Meaning?

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 complex. In patients with CAD, fQRS was associated with myocardial scar detected by single photon emission tomography and was a predictor of cardiac events. fQRS was also a predictor of mortality and arrhythmic events in pati...

Fragmented QRS and prediction of paroxysmal atrial fibrillation episodes

OBJECTIVE Prior studies have demonstrated the relationship between cardiovascular diseases and fragmented QRS (fQRS). fQRS was also associated with ventricular arrhythmias. Our objective was to find out the relationship between fQRS and paroxysmal atrial fibrillation (PAF). METHOD A total of 301 patients without overt structural heart disease were prospectively included in the study. Patients...

Fragmented 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...
