The aims of this study are to assess the clinical benefits resulting from SafeR by comparison with standard dual chamber programming (DDD) with a long atrioventricular (AV) delay.
The benefits will be assessed by comparing the percentage of ventricular pacing, the incidence of atrial arrhythmias, and the evolution of the hemodynamic status as observed through echo parameter and atrial natriuretic peptide/brain natriuretic peptide (ANP/BNP) measurements.

In case of sinus node dysfunction, it is often necessary to choose the safer option provided by a DDD pacemaker even though the most appropriate mode of pacing is AAI mode. In addition to...
1. Background - Pacemaker treatment gives asynchronous activation of the heart that often results in decreased heart function and clinical heart failure. New pacemaker types that...
The investigators propose to carry out an observational study of patients implanted with a pacemaker using AAI SafeR® mode after a TAVI procedure. This study aims to define the persistenc...
The purpose of this study is to assess the incidence (at 90-days) of ventricular pacing in patients undergoing permanent pacemaker placement after TAVR. As well as incidence (at 90-days) ...
Recent studies have shown the importance of preserving spontaneous atrio-ventricular conduction in patients implanted with an implantable cardiac pacemaker. The SafeR/AAISafeR pacing mode...
There have been increasing concerns about the unexpected effects of right ventricular (RV) pacing. We aimed to systematically evaluate the effect of biventricular (BiV) versus RV pacing on clinical ev...
The controversy over electrotherapy for patients aged >80 years occurs already at the stage of qualification for this treatment type and concerns optimal device selection, the implantation strategy, a...
Cardiac pacing can be challenging after a Fontan operation, and limited data exist regarding pacing in adult Fontan patients. The objectives of our study were to determine risk factors for pacing and ...
From 1993 to 2009, nearly 2.9 million pacemakers were implanted in the United States; the majority of which were dual chamber pacemakers. One of the major physiologic advantages of dual chamber pacing...
Atrioventricular junctional (AVJ) ablation and pacemaker implantation is indicated when pharmacotherapy fails to achieve adequate rate control in atrial fibrillation (AF). The purpose of our study is ...
Regulation of the rate of contraction of the heart muscles by an artificial pacemaker.
Moving oneself through space while confused or otherwise cognitively impaired. Patterns include akathisia, exhibiting neuroleptic-induced pacing and restlessness; exit seekers who are often newly admitted institution residents who try to open locked exit doors; self-stimulators who perform other activities such as turning doorknobs, in addition to continuous pacing; and modelers who shadow other pacers.
A type of fluent aphasia characterized by an impaired ability to repeat one and two word phrases, despite retained comprehension. This condition is associated with dominant hemisphere lesions involving the arcuate fasciculus (a white matter projection between Broca's and Wernicke's areas) and adjacent structures. Like patients with Wernicke aphasia (APHASIA, WERNICKE), patients with conduction aphasia are fluent but commit paraphasic errors during attempts at written and oral forms of communication.

Transmission of sound waves through vibration of bones in the SKULL to the inner ear (COCHLEA). By using bone conduction stimulation and by bypassing any OUTER EAR or MIDDLE EAR abnormalities, hearing thresholds of the cochlea can be determined. Bone conduction hearing differs from normal hearing which is based on air conduction stimulation via the EAR CANAL and the TYMPANIC MEMBRANE.
Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
Cardiology is a specialty of internal medicine. Cardiac electrophysiology : Study of the electrical properties and conduction diseases of the heart. Echocardiography : The use of ultrasound to study the mechanical function/physics of the h...
