Relationship between NT-proBNP levels and existing/de novo QRS fragmentation in patients with myocardial infarction

Aim: to assess the evolution of fragmented QRS (fQRS) and NT-proBNP levels during myocardial infarction (MI). Methods: Among 511 patients, 205 (40.1%) had fQRS, with 54 (26.3%) developing de novo fragmentation during hospitalization.

The Positive Effect of Sacubitril-Valsartan Treatment on Frontal QRS-T Angle in Patients with Heart Failure [PDF]

Objective: Introducing angiotensin receptor neprilysin inhibitors (ARNI) to daily clinical practice is one of the most important advances in the treatment of heart failure (HF). ARNI is associated with reduced mortality and hospitalization in HF patients

QRS fragmentation on the 12-lead electrocardiogram and its association to physiological cardiac adaptation in elite cyclists [PDF]

The relationship between electrocardiographic based QRS fragmentation (fQRS) and physiological cardiac adaptation is not fully understood. We aimed to determine the prevalence of fQRS in elite male and female cyclists, and relationship between fQRS and ...

Inferior and anterior QRS fragmentation have different prognostic value in patients who received an implantable defibrillator in primary prevention of sudden cardiac death

, 2017
QRS fragmentation (fQRS) has been proposed as a predictor of sudden cardiac death (SCD) and all-cause mortality in ischemic (ICM) and non-ischemic cardiomyopathy patients. However the value of fQRS in patients with a LVEF

Factor price frontiers with international fragmentation of multistage production [PDF]

This paper investigates international fragmentation in a modeling framework where the multi-stage nature of industrial production is made explicitly, and where the engineering sequence of stages is juxtaposed with a sequence of increasing economic ...

Prediction of response to cardiac resynchronization therapy using electrocardiographic criteria: A systematic review

Revista Portuguesa de Cardiologia
Background: Cardiac resynchronization therapy (CRT) is an established therapeutic option for heart failure, but despite careful selection around 30% of the patients still do not respond to this therapy. The standard electrocardiogram (ECG) is a practical

Malignant ventricular arrhythmias in patients with implantable cardioverter-defibrillators: electrical signals which are predictors of recurrence

CorSalud, 2017
Introduction: There is a growing number of patients with implantable cardioverter-defibrillators. Recurrences are frequent and electrical shocks are the main factor affecting the quality of life. Objective: To identify the electrocardiographic predictors
