Pulsed Field Ablation in Patients With Cardiac Implantable Electric Devices: Vigilance Is Warranted

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Pulsed field ablation (PFA) for the treatment of atrial fibrillation offers potential safety benefits compared to thermal ablation modalities. However, the high voltage electric pulses required to irreversibly electroporate myocardial cells present a unique clinical challenge in regard to patients with cardiac implantable electronic devices ...

Efficacy and Safety of the Sync‐AV II Temporary Cardiac Pacing Catheter (EASY II Trial)

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Cardiac pacing is crucial for patients with hemodynamically unstable bradyarrhythmias. For most indications, transvenous pacemakers are used to pace the right ventricle, causing atrioventricular dyssynchrony, which may lead to significant hemodynamic compromise.

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.

Systolic‐dominant coronary flow in rats and mice: Challenging the diastolic paradigm across conscious and anaesthetized states

Experimental Physiology, EarlyView.
Abstract Extensive research in humans, dogs, rabbits, rats, mice and other mammals has consistently demonstrated that coronary blood flow (CBF) peaks during ventricular diastole. For example, studies using transthoracic Doppler echocardiography in anaesthetized rats and mice, isolated blood‐perfused rat hearts and Doppler probes sutured to the ...

Effect of prophylactic single dose parenteral amiodarone in mitral valve replacement surgery [PDF]

Journal of Research in Applied and Basic Medical Sciences
Background & Aims: Amiodarone is a purposive medicine useful in restoring sinus rhythm (SR) after cardiac surgery. The aim of the study was to evaluate the effect of prophylactic intraoperative single-dose intravenous amiodarone and to convert atrial ...

Atrial fibrillation, sinoatrial and atrioventricular node dysfunction in a mouse model of heart failure with preserved ejection fraction

Experimental Physiology, EarlyView.
Summary of the timeline of characterized events related to atrial fibrilation (AF) and diastolic dysfunction in a mouse heart failure with preserved ejection fraction (HFpEF) model. Three weeks after the initiation of the diet regimen with high fat diet (HFD) and Nω‐nitro‐l‐arginine methyl ester (l‐NAME) in drinking water to induce HFpEF, significantly

Suppression of premature ventricular complexes with the PDE5 inhibitor sildenafil: First clinical experience

Experimental Physiology, EarlyView.
Abstract The phosphodiesterase‐5 inhibitor sildenafil suppresses ventricular arrhythmias in a sheep model of drug‐induced long QT. In that study, ventricular arrhythmias were abolished by reducing premature ventricular complexes (PVCs) and delaying PVC onset, thus preventing ‘R‐on‐T’ ventricular tachycardia.
