Atriofascicular Mahaim with Ebstein anomaly: A case report

Journal of Arrhythmia, 2017
We report a case of a 7-year-old girl with atriofascicular Mahaim (AFM) pathway concomitant with Ebstein's anomaly. The QRS wave showed left bundle branch block pattern on electrocardiogram. Holter electrocardiogram showed prolongation of the PR interval

Age-dependent dynamic electrophysiological field potential behavior of atrioventricular node during experimental AF in rabbit [PDF]

, 2010
Introduction: Electrophysiological studies have demonstrated a relationship between aging and atrioventricular (AV) nodal conduction and refractoriness.

The early stages of heart development: insights from chicken embryos [PDF]

, 2016
The heart is the first functioning organ in the developing embryo and the detailed understanding of the molecular and cellular mechanisms involved in its formation provides insights into congenital malformations affecting its function and therefore the ...

A phenomap of TTR amyloidosis to aid diagnostic screening

ESC Heart Failure, Volume 12, Issue 2, Page 1113-1118, April 2025.
Abstract Cardiac amyloidosis due to transthyretin (ATTR) remains an underdiagnosed cause of cardiomyopathy. As awareness of the disease grows and referrals for ATTR increase, clinicians are likely to encounter more atypical forms of the condition in clinical practice.

A study of the role of nitric oxide in the mechanism of action of hydroalcoholic extract of saffron (Crocus sativus) on the electrophysiological properties of the rabbit atrioventricular node [PDF]

, 2007
Biologically active substances of plant origin represent an essential branch of modern cardiovascular pharmacotherapy. Furthermore, drugs of plant origin have the advantage of weaker adverse effects and lower prices than synthetic drugs.

Connecting the dots: A narrative review of the relationship between heart failure and cognitive impairment

ESC Heart Failure, Volume 12, Issue 2, Page 1119-1131, April 2025.
Abstract Large clinical data underscore that heart failure is independently associated to an increased risk of negative cognitive outcome and dementia. Emerging evidence suggests that cerebral hypoperfusion, stemming from reduced cardiac output and vascular pathology, may contribute to the largely overlapping vascular dementia and Alzheimer's disease ...

Role of nitric oxide on the electrophysiological properties of isolated rabbit atrioventricular node by extracellular field potential during atrial fibrillation [PDF]

, 2011
Introduction: The aim of the present study was to determine direct effects of NO modulation on protective electrophysiological properties of atrioventricular node (AV node) in the experimental model of AF in rabbit.

Morphology and electrophysiology of the mammalian atrioventricular node

Physiological Reviews, 1988
The AV node of those mammalian species in which it has been thoroughly investigated (rabbit, ferret, and humans) consists of various cell types: transitional cells, midnodal (or typical nodal cells), lower nodal cells, and cells of the AV bundle. There are at least two inputs to the AV node, a posterior one via the crista terminalis and an anterior ...

Predicting acute decompensated heart failure using circadian markers from heart rate time series

ESC Heart Failure, EarlyView.
Circadian metrics—amplitude, mesor, and acrophase—derived from a wrist‐worn heart rate monitor can predict acute decompensated heart failure (ADHF) up to 21 days before onset. In 65 post‐ADHF patients, an LSTM model achieved 74% sensitivity, and 73% specificity trained on 21‐day sequences. These findings support circadian rhythm analysis as a promising
