Cardiac resynchronization is an established treatment modality in patients with heart failure NYHA class III-IV on optimal medical treatment, QRS duration of at least 120-130 ms and ejection fraction <35%. Nevertheless, a proportion of patients, up to 20-30%, are considered non-responders as they are not improved by cardiac resynchronization therapy (CRT). This report describes a 63-year-old pa...
Evidence is available that in heart failure, cardiac resynchronization therapy by biventricular pacing improves myocardial function and exercise capacity. Whether this is accompanied by a sustained inhibition of heart failure-dependent sympathoexcitation is uncertain. In 11 heart failure patients (mean+/-SEM age, 68.4+/-1.5 years) in New York Heart Association (NYHA) class III and IV under medi...

Cardiac resynchronization therapy (CRT) is electrical resynchronization of the ventricles. Bachmann's bundle (BB) pacing is considered to be electrical resynchronization of the atria. Atrial fibrillation (AF) and congestive heart failure (HF) often coexist in the same patient. A 69 year-old man who underwent CRT combined with BB pacing for HF and atrial tachycardias or atrial fibrillation (AF) ...
BACKGROUND Cardiac resynchronization therapy (CRT) has become a successful treatment option for symptomatic heart failure in patients with poor left ventricular (LV) systolic function and broad QRS complex in the surface electrocardiogram (ECG). CASE REPORT In this report we present a case of a 70-year-old woman with advanced heart failure due to ischaemic heart disease who underwent an upgra...
It has been firmly established that cardiac resynchronization therapy (CRT) reduces symptoms and improves mortality in patients with moderate-to-severe chronic heart failure [New York Heart Association (NYHA) class III-IV], despite optimal heart failure medication and with wide QRS complex on the surface electrocardiogram as evidence of ventricular dyssynchrony, but not whether such treatment i...
Current guidelines recommend cardiac resynchronization therapy (CRT), previously known as biventricular pacing, in patients with left ventricular (LV) systolic dysfunction (ejection fraction [EF] 35%), QRS prolongation ( 120 ms), and New York Heart Association (NYHA) class III or IV heart failure (HF).1 These recommendations come after multiple prospective, randomized trials demonstrated the be...
Background—Cardiac resynchronization therapy for heart failure with left bundle branch block reduces left ventricular (LV) conduction delay, contraction asynchrony, and LV end-systolic volume (“reverse remodeling”). Up to one third of patients do not improve, and the electric requirements for reverse remodeling are unclear. We hypothesized that reverse remodeling is predicted by the left bundle...

OBJECTIVES Our objective was to evaluate the short-term safety and efficacy of cardiac resynchronization therapy (CRT) in children. BACKGROUND Cardiac resynchronization therapy has been beneficial for adult patients with poor left ventricular function and intraventricular conduction delay. The efficacy of this therapy in the young and in those with congenital heart disease (CHD) has not yet b...
