Paradoxical heart rate response after atropine sulfate administration in total atrioventricular block complicating acute myocardial infarction: A case report

Bali Journal of Anesthesiology, 2021
Acute myocardial infarction is sometimes complicated by atrioventricular block. Advanced cardiac life support guideline for the treatment of atrioventricular block suggests early use of atropine.

Soft and Adhesive Cardiac Patch for Electrophysiological and Contraction Measurement

Advanced Science, EarlyView.
This study developed an epicardial electronic patch with a modulus similar to that of the heart (approximately 65kPa), which can collect stable electrocardiogram signals and myocardial contractility on the surface of a dynamically beating heart. This is attributed to the hydrogen bond interaction formed between the amino and catechol groups in the ...

Nephronectin regulates atrioventricular canal differentiation via Bmp4-Has2 signaling in zebrafish

, 2011
The extracellular matrix is crucial for organogenesis. It is a complex and dynamic component that regulates cell behavior by modulating the activity, bioavailability and presentation of growth factors to cell surface receptors.

Targeting Endogenous Lipophagy: A Novel Strategy to Enhance MSC Osteogenesis and Mineralization for Senile Osteoporosis Therapy

Advanced Science, EarlyView.
Schematic representation of the role of lipophagy in bone mesenchymal stem cells(MSCs). In healthy MSCs, functional lipophagy efficiently degrades lipid droplets to support oxidative phosphorylation and cellular energy production, thereby facilitating osteogenic differentiation and matrix mineralization.

The sophisticated architecture of the rat atrioventricular node [PDF]

, 2005
In the mammalian heart, the action potential spontaneously generated in the sinoatrial (SA) node propagates through the atria to reach the atrioventricular (AV) node.

Worsening Heart Failure From Decreased Atrioventricular Synchronization Rate of a Leadless Pacemaker

JACC: Case Reports
Background: Atrioventricular synchronous pacing with a leadless pacemaker is a therapy used in patients with atrioventricular block. However, atrial oversensing may cause an increase in heart rate, with resulting atrioventricular dyssynchrony.

The Homozygous p.(Arg215Ter) Variant in XRCC2 Is Associated With Atypical Fanconi Anemia Without Major Hematological Abnormalities in Childhood

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Fanconi Anemia (FA) is the most frequent inherited bone marrow failure syndrome. A role for the XRCC2 gene in FA was suspected in 2012 and confirmed in 2016, but only two affected individuals have been described thus far, and no long‐term follow‐up is available.

Atresia of the right atrioventricular orifice with atrioventricular concordance. [PDF]

Heart, 1979
Three hearts are described in which a fibrous membrane was interposed between the right atrium and a formed but hypoplastic right ventricle, which possessed recognisable inlet, trabecular, and infundibular components. In these hearts the distribution of the conducting tissue was as expected for concordant atrioventricular connections, and contrasts ...

Co‐Occurring Non‐Cardiac Congenital Anomalies Among Cases With Congenital Heart Defects

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cases with congenital heart defects (CHD) often have other associated anomalies. The aim of this investigation was to assess the prevalence and the types of co‐occurring anomalies in CHD in a well‐defined population. The anomalies co‐occurring with CHD were ascertained in all live births, stillbirths and terminations of pregnancy for fetal ...
