From Atrial Fibrillation to Ventricular Fibrillation and Back [PDF]

Circulation, 2015
A 27-year-old man without any previously known health conditions was found unresponsive on the street after he had been exercising. Cardiopulmonary resuscitation was started by bystanders. On arrival of the emergency services, the rhythm strip in Figure 1A was recorded.

Impact of atrial fibrillation on the risk of death: the Framingham Heart Study.

Circulation, 1998
BACKGROUND Atrial fibrillation (AF) causes substantial morbidity. It is uncertain whether AF is associated with excess mortality independent of associated cardiac conditions and risk factors. METHODS AND RESULTS We examined the mortality of subjects 55

Progression of Atrial Fibrillation after Cryoablation or Drug Therapy.

New England Journal of Medicine, 2022
BACKGROUND Atrial fibrillation is a chronic, progressive disorder, and persistent forms of atrial fibrillation are associated with increased risks of thromboembolism and heart failure.

The safety of direct transeptal puncture using a radiofrequency guidewire combined with a 17Fr pulsed field ablation sheath

Scientific Reports
Transseptal puncture (TSP) is widely used in catheter-based cardiac interventions to gain left atrial (LA) access, but its workflow has remained largely unchanged and is still a source of serious complications.

Polymorphism in alpha-synuclein oligomers and its implications in toxicity under disease conditions

Frontiers in Molecular Biosciences, 2022
The major hallmark of Parkinson’s disease (PD) is represented by the formation of pathological protein plaques largely consisting of α-synuclein (αSN) amyloid fibrils.

Dynamic fibrils in H-alpha and C IV [PDF]

Astron.Astrophys.460:309-316,2006, 2007
Aim: To study the interaction of the solar chromosphere with the transition region, in particular active-region jets in the transition region and their relation to chromospheric fibrils. Methods: We carefully align image sequences taken simultaneously in C IV with the Transition Region and Coronal Explorer and in H-alpha with the Swedish 1-m Solar ...

Atrial fibrillation

Australian Journal of General Practice, 2019
Abstract Atrial fibrillation (AF) is the commonest cardiac arrhythmia in hospitalized patients, with an increasing incidence with age and an epidemic increase projected for the next 10 years. Therapy of AF has several goals: to decrease mortality (mainly due to cardiovascular diseases), stroke rate, ventricular deterioration, and heart ...

Catheter ablation of atrial fibrillation in patients with diabetes mellitus

Heart Rhythm O2, 2020
Background: Diabetes mellitus (DM) is an independent risk factor for atrial fibrillation (AF). Few studies have compared clinical outcomes after catheter ablation between patients with and those without DM.
