Higher ventricular rate during atrial fibrillation relates to increased cerebral hypoperfusions and hypertensive events [PDF]

Scientific Reports, 9: 3779, 2019, 2019
Atrial fibrillation (AF) is associated with cognitive impairment/dementia, independently of clinical cerebrovascular events (stroke/TIA). One of the plausible mechanisms is the occurrence of AF-induced transient critical hemodynamic events; however, it is presently unknown, if ventricular response rate during AF may impact on cerebral hemodynamics.

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Fusion rules for pastures and tracts [PDF]

arXiv, 2021
Baker and Bowler defined a category of algebraic objects called tracts which generalize both partial fields and hyperfields. They also defined a notion of weak and strong matroids over a tract $F$, and proved that if $F$ is perfect, meaning that $F$-vectors and $F$-covectors are orthogonal for every matroid over $F$, then the notions of weak and strong

Ablation of Outflow Tract Arrhythmias in Patients With and Without Structural Heart Disease—A Comparative Analysis

Frontiers in Cardiovascular Medicine, 2022
IntroductionCatheter ablation of ventricular arrhythmias emerging from the ventricular outflow tracts and adjacent structures is very effective and considered almost curative in patients without structural heart disease (SHD).
