Werner Irnich: Pioneer in the Development of the Dual‐Chamber Pacemaker—An Obituary

open access: yesPacing 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

Zero‐Fluoroscopy Ablation Methods for Atrial Fibrillation: A Systematic Review and Meta‐Analysis

open access: yesPacing and Clinical Electrophysiology, EarlyView.
Central illustration. Schematic comparison of conventional fluoroscopy guided ablation (left) and zero fluoroscopy ablation (right), enabled by electroanatomical mapping and intracardiac echocardiography for catheter navigation without X ray. The study selection process is summarized (133 records identified; 12 studies included, total n = 1998 ...

A Stepwise ECG Algorithm to Resolve Identical Precordial Transition in Idiopathic Outflow Tract Ventricular Arrhythmias

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Accurate pre‐procedural differentiation of right (RVOT) versus left ventricular outflow tract (LVOT) origin in idiopathic outflow tract ventricular arrhythmias may facilitate procedural planning and mapping strategy. However, existing 12‐lead ECG criteria show variable performance and often fail to provide clear discrimination when ...

Ventricular Synchrony in Targeted Right Ventricular Septal Pacing: A Prospective Paired Comparison to Apical Placement

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background/Objectives Right ventricular (RV) apical pacing, the standard pacing approach, often induces ventricular dyssynchrony, potentially impairing cardiac function. This study aims to investigate whether targeted RV septal pacing, guided by functional electrophysiological feedback during implantation, reduces ventricular dyssynchrony ...

Diagnostic Accuracy of 12‐Lead ECG Algorithms for Accessory Pathway Localization in WPW: A Meta‐Analysis

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background In Wolff–Parkinson–White (WPW) syndrome, accurate localization of accessory pathways before catheter ablation can improve procedural planning and efficiency. Several 12‐lead electrocardiographic (ECG) algorithms have been proposed, but their diagnostic performance has not been consistently established.

Management of Left Atrial Appendage Thrombi and Spontaneous Echo Contrast

open access: yesPacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background To analyze the efficacy and safety of various anticoagulation strategies/regimen used for managing thrombus or spontaneous echo contrast in the left atrial appendage. Methods Thrombus or spontaneous echo contrast in the left atrial appendage was detected via transesophageal echocardiography in 83 patients, most often during a stroke

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges

open access: yesExperimental 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.

Cerebral blood flow regulation, central arterial stiffness and traumatic brain injury: Effects of aerobic exercise training

open access: yesExperimental Physiology, EarlyView.
Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...

Brain strain: Blood flow and metabolism in environmental extremes

open access: yesExperimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...
