Background Cardiac resynchronization therapy (CRT) is a successful strategy for heart
failure (HF) patients. The pre-requisite for the response is the evidence of electrical …

Background Several studies have investigated the association between native QRS duration
(QRSd) or QRS narrowing and response to biventricular pacing. However, their results have …

Background Cardiac resynchronization therapy (CRT) reduces mortality and morbidity in
selected heart failure patients. However, not all patients respond to CRT. Objective We …

Electrocardiogram (ECG) monitoring has been widely explored in detecting and diagnosing
cardiovascular diseases due to its accuracy, simplicity, and sensitivity. However, medical-or …

Background We investigated whether reversed electrical remodeling (RER), defined as
narrowing of the native electrocardiographic QRS duration after cardiac resynchronization …

Background Cardiac resynchronization therapy (CRT) is a highly effective treatment in
patients with a class I recommendation. However, a small proportion of the strictly selected …

Introduction Amiodarone reduces recurrent ventricular tachyarrhythmias (VTA) but may
worsen cardiovascular outcomes in heart failure (HF) patients. Cardiac resynchronization …

Background Cardiac resynchronization therapy (CRT) is an established treatment in
selected patients suffering from heart failure with reduced ejection fraction (HFrEF). It has …

Background Heart failure is associated with ventricular dyssynchrony and energetic
inefficiency, which can be alleviated by cardiac resynchronization therapy (CRT) with …

The prevalence of heart failure is increasing and it is associated with significant mortality
and morbidity. Optimal medical therapy improves outcome, but heart failure continues to …
