Complete atrioventricular block during neonatal intubation: a case report

Resuscitation Plus
Preterm infants often experience side effects from intubation. Desaturation and sinus bradycardia are frequent. Atropine as premedication mitigates these risks.We report the occurrence of severe bradycardia related to atrioventricular block during ...

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

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.

Rate-dependent and antiarrhythmic reentrant tachycardia (AVNRT) effects of simvastatin in isolated rabbit atrioventricular nodal model [PDF]

, 2010
Background and purpose: Several previous studies have shown the direct and indirect effects of statins on supraventricular and ventricular arrhythmia. The purpose of the present study is to determine (1) whether Simvastatin modifies the rate-dependent ...

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 ...

Feasibility and Efficacy of His Bundle Pacing or Left Bundle Pacing Combined With Atrioventricular Node Ablation in Patients With Persistent Atrial Fibrillation and Implantable Cardioverter‐Defibrillator Therapy

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Persistent atrial fibrillation may lead to a higher probability of inappropriate shocks in heart failure patients with an implantable cardioverter‐defibrillator (ICD). The aim of this study was to evaluate the impact of His‐Purkinje conduction

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.

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 ...

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
