Holter monitoring in patients with transient and focal ischemic attacks of the brain [PDF]

, 1986
The results of Holter monitoring in 100 patients with transient and focal cerebral ischemia were studied retrospectively. Atrial fibrillation (AF) was found in five patients compared with two from a group of 100 age and sex-matched control patients. Four

Insulin signaling is critical for sinoatrial node maintenance and function

Experimental and Molecular Medicine, 2023
Insulin and insulin-like growth factor 1 (IGF-1) signaling regulate cellular growth and glucose metabolism in the myocardium. However, their physiological role in the cells of the cardiac conduction system has never been explored. Therefore, we sought to

A photoisomerizable muscarinic antagonist. Studies of binding and of conductance relaxations in frog heart [PDF]

, 1982
These experiments employ the photoisomerizable compound, 3,3'-bis- [alpha-(trimethylammonium)methyl]azobenzene (Bis-Q), to study the response to muscarinic agents in frog myocardium. In homogenates from the heart, trans-Bis-Q blocks the binding of [3H]-N-

Mitochondrial dysfunction on sinoatrial node and pulmonary vein electrophysiological activities

Experimental and Therapeutic Medicine, 2017
Atrial fibrillation (AF) is associated with mitochondrial dysfunction. Sinoatrial node (SAN) dysfunction increases arrhythmogenesis of pulmonary veins (PVs), which is the most important trigger of AF; however, it is not clear whether mitochondrial dysfunction differentially regulates electrical activity of SANs and PVs.

Cardiac disease in systemic sclerosis: Integrating pathobiology with clinical management

Rheumatology &Autoimmunity, EarlyView.
Abstract Systemic sclerosis (SSc) is a complex autoimmune disorder in which cardiovascular involvement remains a major determinant of morbidity and mortality. Cardiac injury in SSc results from the interplay of microvascular dysfunction, immune‐mediated inflammation, and progressive interstitial and replacement fibrosis, leading to myocardial disease ...

Rare Case of Rapidly Worsening REM Sleep Induced Bradycardia

Case Reports in Cardiology, 2015
Sinoatrial arrest also known as sinus pause occurs when sinoatrial node of the heart transiently ceases to generate the electrical impulse necessary for the myocardium to contract. It may last from 2.0 seconds to several minutes. Etiologies of sinoatrial

Effect of selective heart rate slowing in heart failure with preserved ejection fraction [PDF]

, 2015
Background Heart failure with preserved ejection fraction (HFpEF) is associated with significant morbidity and mortality but is currently refractory to therapy.

Pulsed Field Ablation for Atrial Fibrillation in Patients With Obesity: Procedural and Clinical Outcomes

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Procedural and clinical outcomes in patients with obesity undergoing catheter ablation for atrial fibrillation (AF) have been mixed. Clinical data in the context of pulsed field ablation (PFA) are currently limited in this patient cohort.

Use of machine learning and Poincaré density grid in the diagnosis of sinus node dysfunction caused by sinoatrial conduction block in dogs

Journal of Veterinary Internal Medicine
Background Sinus node dysfunction because of abnormal impulse generation or sinoatrial conduction block causes bradycardia that can be difficult to differentiate from high parasympathetic/low sympathetic modulation (HP/LSM).
