Impact of Heat Stress on Electrocardiographic Changes in New Zealand White Rabbits [PDF]

Journal of Stress Physiology & Biochemistry, 2013
A study was conducted on twelve clinically normal and healthy New Zealand White rabbits of both sexes, weighing between 2-3 kg, and aged between 1-3 years to observe the normal electrocardiogram and its changes during heat stress.

Clinical Anatomy of the Left and Right Atrial Appendages in Humans: Comparative and Developmental Perspective

Clinical Anatomy, EarlyView.
ABSTRACT Human atrial chambers derive from distinct embryonic anlagens, the original embryonic atria gradually transforming into the so‐called auricles, or atrial appendages. This study quantifies macroscopic variations in pectinate muscle architecture in human atrial appendages and evaluates their visualization using clinical imaging modalities.

Idiopathic Ventricular Fibrillation — Just How Much Idiopathic is it?

Reviews in Cardiovascular Medicine
Idiopathic ventricular fibrillation is diagnosed in survivors of sudden cardiac death that has been caused by ventricular fibrillation without known structural or electrical abnormalities, even after extensive investigation.

Transcatheter Repair of Sinus Venosus Defect Using a 12‐zig Covered Cheatham‐Platinum Stent in Large Superior Vena Cava—Right Atrium Junctions: Early Multicenter Experience

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Sinus venosus defect (SVD) is a rare congenital heart anomaly characterised by an abnormal communication between the atria, often associated with partial anomalous pulmonary venous connection (PAPVC). Traditional surgical repair carries significant risks, prompting exploration into less invasive transcatheter approaches.

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]

, 2012
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

Exercise training corrects control of spontaneous calcium waves in hearts from myocardial infarction heart failure rats [PDF]

, 2011
Impaired cardiac control of intracellular diastolic Ca²⁺ gives rise to arrhythmias. Whereas exercise training corrects abnormal cyclic Ca²⁺ handling in heart failure, the effect on diastolic Ca<sup>2 ...

Left atrial appendage thrombosis in a patient with Friedreich Ataxia–related cardiomyopathy, left ventricular systolic dysfunction, and atrial fibrillation

SAGE Open Medical Case Reports, 2021
Friedreich ataxia is the most common form of hereditary ataxia. Heart involvement in Friedreich ataxia is common and can include increased left ventricular wall thickness, atrial fibrillation, and in the later stages, a reduction of left ventricular ...

Pre‐Existing and New‐Onset Atrial Fibrillation in Patients Undergoing Transcatheter Aortic Valve Implantation

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Atrial fibrillation (AF) is a frequent comorbidity in patients with severe aortic valve stenosis undergoing transcatheter aortic valve implantation (TAVI). In addition, new‐onset AF can occur after TAVI. However, data on how AF affects outcomes in patients undergoing TAVI remain conflicting.

Influence of the Residual Gensini Score on Prognosis of Patients With ST‐Elevation Myocardial Infarction

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background The residual Gensini score (rGS) was developed to quantify the severity of coronary atheroma burden after coronary revascularisation. The predictive value of the rGS for clinical outcomes in patients with ST‐segment elevation myocardial infarction (STEMI) remains unexplored.
