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

Dynamics and Cardiac Arrhythmias
Journal of Cardiovascular Electrophysiology, 2006Cardiac arrhythmias, characterized by single or multiple reentrant circuits, represent a dynamic phenomenon in an excitable medium. In this review, we provide a brief overview of how cardiac action potential duration restitution, conduction velocity restitution, and intracellular calcium cycling regulate the dynamics of action potential excitation and ...

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.

Mechanisms of Cardiac Arrhythmias
Revista Española de Cardiología (English Edition), 2012Cardiac arrhythmias are prevalent among humans across all age ranges and may occur in the setting of underlying heart disease as well as in structurally normal hearts. While arrhythmias are widely varied in their clinical presentations, they possess shared electrophysiologic properties at the cellular level.

Cardiac arrhythmias in pregnancy
Seminars in Perinatology, 2014As more women with repaired congenital heart disease survive to their reproductive years and many other women are delaying pregnancy until later in life, a rising concern is the risk of cardiac arrhythmias during pregnancy. Naturally occurring cardiovascular changes during pregnancy increase the likelihood that a recurrence of a previously experienced ...

Mechanisms for cardiac arrhythmias
Experientia, 1987Possible cellular electrophysiological mechanisms for arrhythmias have been investigated through studies of isolated cardiac tissues. Records through extracellular and intracellular electrodes indicate that arrhythmias may result from either focal or non-focal mechanisms.

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.

Postgraduate Medicine, 1983
Cardiac arrhythmias often call for emergency treatment, and often it is the primary care physician who must respond quickly and effectively. In this article, Dr Brent reviews the various types of arrhythmias and the methods available for dealing with them on an emergency basis. According to one peer reviewer, this article contains "the information that

The genesis of cardiac arrhythmias
Progress in Cardiovascular Diseases, 1966HIS PAPER will be concerned with several general mechanisms which are thought to be causes of disturbances of cardiac rhythm. Possible mechanisms operative in the genesis of specific arrhythmias encountered in the clinic will not be considered. The reasons for this approach are several. The information derived from experiment, which forms the basis for
