Impact of Leadless Pacemaker Implantation Position on Subclinical Right Ventricular Perforation
Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Introduction Leadless pacemakers are typically implanted in the mid‐septum of the right ventricle (RV) to mitigate the risk of perforation. However, reports on the precise location of these implants are limited. This study aimed to elucidate tine‐based leadless pacemaker position and presence of subclinical RV perforation through computed ...

Oman Medical JournalIt has been hypothesized that increased intracranial pressure (ICP) may cause sick sinus syndrome (SSS) due to its effect on vagal discharge to the heart, resulting in disruption to the sinus cycle, despite age-related degeneration of the sinoatrial node

QT Interval Evaluation in Right Ventricular Pacing: Validation of a Novel Formula
Pacing and Clinical Electrophysiology, EarlyView.Abstract Background QT interval measurement in the presence of right ventricular pacing (RVP) represents a clinical challenge. We therefore aimed to derive and validate a formula for QT estimation during RVP in a large cohort of pacemaker patients. Methods and Results We prospectively enrolled 100 patients in a derivation cohort and 487 in a validation

Importance of maintained atrio-ventricular synchrony in patients with pacemarkers [PDF]
, 2017 The effect of atrial contraction on cardiac function is reviewed in patients with dual chamber and rate-responsive ventricular pacemakers. The question posed was is there any haemodynamic, clinical or prognostic advantage of AV synchrony in dual chamber ...

Werner Irnich: Pioneer in the Development of the Dual‐Chamber Pacemaker—An Obituary
Pacing and Clinical Electrophysiology, EarlyView.ABSTRACT Fifty years ago, Werner Irnich presented the concept of an optimal pacemaker capable of responding appropriately to various cardiac arrhythmias and perceptual disturbances, and intended to be used in 85% of patients. With this concept, Irnich was far ahead of his time. His proposed circuitry for AV block and atrial fibrillation, as well as his

Emerging risk factors influencing the occurrence of peri‐implantitis
Periodontology 2000, EarlyView.Abstract Background The objective of the present review is to explore the evidence and biological plausibility of factors that may expose dental implants to a greater likelihood of developing peri‐implantitis. Material and Methods An electronic screening on the PubMed library the was carried out to identify potential emerging factors that influence the

Simultaneous mesoscopic and two-photon imaging of neuronal activity in cortical circuits. [PDF]
, 2020 Spontaneous and sensory-evoked activity propagates across varying spatial scales in the mammalian cortex, but technical challenges have limited conceptual links between the function of local neuronal circuits and brain-wide network dynamics. We present a

The role of neutrophils in the pathophysiology of inflammatory bowel diseases
Periodontology 2000, EarlyView.Abstract Objectives Inflammatory bowel disease (IBD) encompasses a spectrum of chronic disorders of the gastrointestinal tract, with a potential bidirectional relationship with periodontitis. Neutrophils are key regulators of immune‐inflammatory responses and play a major role in both diseases.

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges
Experimental Physiology, EarlyView.Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.
