Hypocalcemia and Cardiac Arrhythmias
Archives of Pediatrics & Adolescent Medicine, 1968THE BEST KNOWN clinical effect on the heart of hypocalcemia is prolongation of the QT interval, ie, prolongation of electrical systole.1-6Only recently has cardiac arrhythmia been reported as a clinical manifestation of hypocalcemia.7,8This report describes a child with hypocalcemic vitamin D deficient rickets who presented with bizarre cardiac ...

Electroimmunology and cardiac arrhythmia
Nature Reviews Cardiology, 2021Conduction disorders and arrhythmias remain difficult to treat and are increasingly prevalent owing to the increasing age and body mass of the general population, because both are risk factors for arrhythmia. Many of the underlying conditions that give rise to arrhythmia - including atrial fibrillation and ventricular arrhythmia, which frequently occur

Surgery for cardiac arrhythmias
Current Opinion in Cardiology, 1994The field of arrhythmia surgery has changed markedly over the past several years. The increased effectiveness of catheter ablation for the treatment of supraventricular tachycardias, the increasingly common use of surgical techniques for treating atrial fibrillation, and the continued refinement of implantable cardioverter-defibrillator technology have

Stroke and cardiac arrhythmias
Journal of Stroke and Cerebrovascular Diseases, 2002Stroke is frequently followed by electrocardiographic (ECG) changes. The aim of the present study was to evaluate the global incidence of these changes after ischemic or hemorrhagic strokes, but it focused on cardiac arrhythmias. In ischemic strokes, these were correlated with the side of the lesion(s).

Veterinary Clinics of North America: Equine Practice, 2019
Arrhythmias are common in horses. Sinus arrhythmia and first- and second-degree atrioventricular block are frequently found physiologic arrhythmias, but should immediately disappear after stress or exercise. Atrial premature depolarizations are usually not associated with poor performance, but are a potential trigger for atrial fibrillation.

Cardiac arrhythmias and the athlete
Current Opinion in Cardiology, 1999Athletes, although the healthiest segment of society, can develop cardiac arrhythmias. Benign bradycardias and atrial and ventricular premature contractions are common and seldom require treatment. Supraventricular tachycardias are less common and are usually not life-threatening, but do require treatment.

Proceedings of the 1991 ACM/IEEE conference on Supercomputing - Supercomputing '91, 1991
To understand the behavior of the heart under chaotic conditions, a computer simulation was made considering it as coupled biological oscillators. Piece-wise linear and non-linear equations were used to characterize the observed phase response behavior of the myocardial cells.

Hypertension and Cardiac Arrhythmias
Current Pharmaceutical Design, 2007Arterial hypertension is a widespread disease and one of important yet under-recognized and under-treated causes of atrial and ventricular arrhythmias. Hypertrophy of cardiac muscle in hypertensive patients is characterized not only by increased myocardial mass, but also by proliferation of fibrous tissue and decreased intercellular coupling, that lead

Alcohol and Cardiac Arrhythmias
Alcoholism: Clinical and Experimental Research, 1998Chronic alcohol overconsumption increases the risk for sudden death presumably due to ventricular arrhythmias. This paper is a review of the mechanisms behind alcohol‐induced arrhythmias and describe the incidence of alcohol‐related ventricular arrhythmias.
