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...
AV conduction abnormalities are observed in 15-30% of patients with hypertrophic cardiomyopathy but are usually not severe enough to require permanent pacemaker implant. Both septal myectomy and alcoh...
Conventional transvenous pacemaker and ICD-therapy is associated with significant lead- and pocket-related problems. Leadless pacemaker and subcutaneous ICD (S-ICD) therapies are innovative technologi...
Late-onset pacemaker-related pleural effusions (PEs) are rare and are often misdiagnosed with other entities. Our study aimed to detail the clinical features and management of PEs long after pacemaker...
Impact of Physiologic Pacing Versus Right Ventricular Pacing Among Patients With Left Ventricular Ejection Fraction Greater Than 35%: A Systematic Review for the 2018 ACC/AHA/HRS Guideline on the Evaluation and Management of Patients With Bradycardia and Cardiac Conduction Delay.
It is unclear whether physiologic pacing by either cardiac biventricular pacing (BiVP) or His-bundle pacing (HisBP) may prevent adverse structural and functional consequences known to occur among some...
This study explores the feasibility of left bundle branch pacing (LBBP) and characterizes electrocardiogram (ECG) patterns during the pacing in comparison with conventional right ventricular pacing (R...
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.
Diseases characterized by pathological irregularities in the HEART CONDUCTION SYSTEM. They may be associated with other heart diseases and syndromes (e.g., BRUGADA SYNDROME; NEUROMUSCULAR DISEASE, HEART BLOCKS), isolated or may result from injuries. You can have a conduction disorder without having an arrhythmia, but some arrhythmias arise from conduction disorders. OMIM: 601144.
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.
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...
