Atrioventricular block precipitated by isoproterenol

, 2015
An isoproterenol infusion was administered during an electrophysiologic study (EPS) in a patient with a history of near syncope, left bundle branch block, and no documented atrioventricular (AV) block.

The first case of Reel Syndrome in a dog after pacemaker implantation: A case report

Australian Veterinary Journal, EarlyView.
Reel Syndrome is a rare complication of permanent pacemaker implantation, characterised by the rotation of the device around its transverse axis, which causes the lead to coil around the generator and displacement, leading to pacing dysfunction. This report presents the first documented case of Reel Syndrome in a dog.

A novel selective stabilizer of the ryanodine receptor 2 prevents stress‐induced ventricular arrhythmias without impairing cardiac function

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Aberrant activation of type 2 ryanodine receptors (RyR2) causes lethal arrhythmias, such as catecholaminergic polymorphic ventricular tachycardia (CPVT). Developing drugs that suppress RyR2 hyperactivation may be key to novel arrhythmia treatments.

Third-Degree Atrioventricular Block Due to Chloroquine Treatment

, 2011
A 67-year-old woman on long-term chloroquine treatment for rheumatoid arthritis presented with dizziness and syncope. Although her medical history revealed no cardiovascular disease, complete atrioventricular block was detected by electrocardiography ...

Diltiazem N‐oxide, a novel ischaemia‐activated prodrug, prevents ischaemia‐induced ventricular fibrillation without off‐target adverse effects

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ventricular fibrillation (VF) in coronary heart disease accounts for up to 70% of sudden cardiac death. We examined whether diltiazem N‐oxide (DNO) has ischaemia‐selective antiarrhythmic activity. Experimental Approach Randomised and blinded experiments were performed in rat isolated hearts and in anaesthetised rats to ...

Transient atrioventricular block following catheter radiofrequency sinus node modification [PDF]

, 2007
Complete atrioventricular block, second-degree Mobitz type II and first-degree atrioventricular block with right bundle branch block were observed consecutively following successful radiofrequency ablation in close proximity to the sinus node.

Progressive fetal atrioventricular block in heterotaxy syndrome

, 2007
We report a fetus with left isomerism, in whom the atrioventricular block progressed from low grade second degree to complete block and fetal hydrops. While it is known that there is a high incidence of heart block in the fetus with left isomerism, as ...

Cardiovascular toxicity from immune checkpoint inhibitor therapy: an inflammatory continuum

British Journal of Pharmacology, EarlyView.
Immune checkpoint inhibitor (ICI) therapy has markedly improved outcomes in advanced malignancies but has also revealed a distinct spectrum of cardiovascular immune‐related adverse events. Myocarditis represents the most severe manifestation, while non‐inflammatory left ventricular dysfunction and vascular inflammation have emerged as additional ...

Agreement of the performance of equine electrocardiogram recording devices for ECG complexity analysis

Equine Veterinary Journal, EarlyView.
Abstract Background Non‐linear equine electrocardiography (ECG) analysis is an actively developing study area which has the potential to lead to novel, artificial intelligence‐based diagnostic tools in equine cardiology. As more ECG recording devices are becoming available, there is a need to ensure results are interchangeable regardless of the ...
