Transient severe conduction disturbances associated with ankylosing spondylitis

Journal of Arrhythmia, 2019
A 46‐year‐old man presented with advanced and complete atrioventricular block. He was diagnosed with human leukocyte antigen‐B27‐positive ankylosing spondylitis (AS) and treated with nonsteroidal anti‐inflammatory drugs for AS.

Novel Electroactive Therapeutic Platforms for Cardiac Arrhythmia Management

Advanced Science, EarlyView.
Electroactive platforms offer promising applications in cardiac arrhythmia. Based on their energy sources and mechanisms, electroactive platforms are categorized into i) direct electrical stimulation, ii) self‐powered electroactive systems, iii) physical stimuli‐mediated electroactive systems, and iv) conductive systems, and their applications in ...

Sleep quality and quantity determined by polysomnography in mechanically ventilated critically ill patients randomized to dexmedetomidine or placebo

Acta Anaesthesiologica Scandinavica, Volume 67, Issue 1, Page 66-75, January 2023., 2023
Abstract Background Abnormal sleep is commonly observed in the ICU and is associated with delirium and increased mortality. If sedation is necessary, it is often performed with gamma‐aminobutyric acid agonists such as propofol or midazolam leading to an absence of restorative sleep.

Atrioventricular Block in Children

Педиатрическая фармакология, 2018
Rhythm and conduction disorders of the heart occupy one of the leading places in the structure of cardiovascular pathology in children. Atrioventricular block is the slowing down or loss of impulses from the atria to the ventricles.

Model-based Estimation of AV-nodal Refractory Period and Conduction Delay Trends from ECG [PDF]

arXiv, 2023
Atrial fibrillation (AF) is the most common arrhythmia, associated with significant burdens to patients and the healthcare system. The atrioventricular (AV) node plays a vital role in regulating heart rate during AF, but is often insufficient in regards to maintaining a healthy heart rate.

In vivo toxic and lethal cardiorespiratory effects of a synthetic quaternary ammonium salt derivative of haloperidol in mice

Animal Models and Experimental Medicine, EarlyView.
Hematoxylin–eosin (H&E) stains of the heart, liver, lung, and kidney show acute toxicity. Abstract Background To investigate the toxicity of N‐n‐butyl haloperidol iodide (F2), a quaternary ammonium salt derivative of haloperidol, in mice for potential therapeutic purposes. Methods The acute median lethal dose (LD50) of F2 was determined using the Bliss

Repeated complete atrioventricular block during remifentanil administration in a pediatric patient with brain tumor and acute hydrocephalus: a case report

BMC Anesthesiology
Background Remifentanil, an ultra-short-acting µ-opioid receptor agonist, is commonly used for anesthetic management due to excellent adjustability. Remifentanil is known to cause sinus bradycardia, however, because it has a direct negative chronotropic ...

Case of reversible Mobitz type II atrioventricular block after the use of injectable antipsychotics

Clinical Case Reports, 2022
Although Mobitz type II atrioventricular block is typically an arrhythmia arising from a permanent organic disorder of the His‐Purkinje system, reversible factors should also be considered. Here, we report the association between a rare reversible Mobitz

The importance of the pericardium for cardiac biomechanics: From physiology to computational modeling [PDF]

, 2018
The human heart is enclosed in the pericardial cavity. The pericardium consists of a layered thin sac and is separated from the myocardium by a thin film of fluid. It provides a fixture in space and frictionless sliding of the myocardium. The influence of the pericardium is essential for predictive mechanical simulations of the heart. However, there is

Identifying the culprit artery via 12‐lead electrocardiogram in inferior wall ST‐segment elevation myocardial infarction: A meta‐analysis

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Sometimes the easiest way is the best. Simple methods as ST‐segment elevation in III > II and ST‐segment depression in aVL > I are effective diagnostic test for identifying culprit artery in inferior wall ST‐segment elevation myocardial infarction. Complex algorithms are not superior to simple methods.
