The number of patients with atrial fibrillation and congestive heart failure has steadily increased in the United States. The presence of atrial fibrillation increases morbidity and mortality for patients with left ventricular dysfunction. The emergence of cardiac resynchronization therapy to improve symptoms and survival from congestive heart failure may provide benefits for those with atrial ...

Cardiac resynchronization therapy (CRT) is an important therapy for patients with heart failure and conduction pathology, but the benefits are heterogeneous between patients and approximately a third of patients do not show signs of clinical or echocardiographic response. This calls for a better understanding of the underlying conduction disease and resynchronization. In this review, we discuss...

Cardiac resynchronization therapy (CRT) has become a mainstay of heart failure treatment. Since heart failure is a disease primarily affecting older patients it is important to evaluate the performance of CRT in this population. Elderly has been suggested as a subgroup less likely to benefit from CRT. This is an important issue that should be clarified, because most patients with heart failure ...

Cardiac pacing is the only effective treatment for patients with sick sinus syndrome and atrioventricular conduction disorders. In cardiac pacing, the endocardial pacing lead is typically positioned at the right ventricular (RV) apex. At the same time, there is increasing indirect evidence, derived from large pacing mode selection trials and observational studies, that conventional RV apical pa...

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) ...

Optimization of cardiac resynchronization therapy is increasingly performed. Numerous methods have been proposed, many being echocardiographic. Both the technique and the timing of optimization are contentious. Whether acute haemodynamic benefits translate into long-term improvements in remodelling, symptoms, or prognosis is unknown. Recent guidelines from the American Society of Echocardiograp...

Ventricle to ventricle (VV) delay optimization can provide an additional benefit to cardiac resynchronization therapy, but the methods currently used for optimization are time consuming and operator-dependent. We present two cases of VV-delay optimization with the use of a new intracardiac electrogram method. (Cardiol J 2007; 14: 305-310).
