Atrial fibrillation and atrial cardiomyopathies

Journal of Cardiovascular Electrophysiology, 2021
AbstractAtrial fibrillation (AF) is the most common arrhythmia among adults. While there have been incredible advances in the management of AF and its clinical sequelae, investigation of atrial cardiomyopathies (ACMs) is becoming increasingly more prominent.

Atrial Fibrillation

Emergency Medicine Clinics of North America, 2011
Atrial fibrillation (AF) results from the chaotic depolarization of atrial tissue and is the most common dysrhythmia diagnosed in United States (US) emergency departments. AF affects greater than 1% of the general population, with a peak prevalence of 10% in those greater than 80 years of age. By 2050, it is estimated that nearly 16 million US patients

Atrial Flutter, Atrial Fibrillation, and Other Primary Atrial Tachycardias

Medical Clinics of North America, 1984
Traditional classifications of atrial tachycardias include not only rhythm disturbances arising primarily within the atria, but also dysrhythmias in which it is now recognized that participation of both atrial and non-atrial tissue is required. We prefer to consider those arrhythmias in which the atria are the principal site of electrophysiologic ...

Atrial Mechanics, Atrial Cardiomyopathy and Impact of Atrial Interventions

Journal of Cardiac Failure
Our comprehension of atrial mechanics, atrial cardiomyopathy and their clinical implications across various cardiovascular conditions has advanced significantly. Atrial interventions can have differing effects on atrial mechanics. With the rapid increase in the use of atrial interventions, it is crucial for investigators and clinicians to acknowledge ...

Termination of Atrial Flutter and Atrial Tachycardia With Rapid Atrial Stimulation

Angiology, 1975
The results in this series of fifty-seven patients confirms the safety and reliability of rapid atrial stimulation to terminate atrial flutter and atrial tachycardia. Transthoracic wires implanted at thoracotomy or transvenously placed atrial electrodes can be used for the confident intracardiac electrocardiographic diagnosis of tachyarrhythmias and ...

Atrial and Ventricular Pressures in Atrial Flutter

Pacing and Clinical Electrophysiology, 1999
The hemodynamic effects of atrial flutter (AF) are unknown. The purpose of the present study was to investigate the changes in atrial and ventricular pressures after induction of AF. In 23 patients with paroxysmal AF (age 59 ± 9 years), a hemodynamic study was performed both during sinus rhythm and after induction of the tachyarrhythmia.

Atrial Electrograms and the Characterization of Atrial Fibrillation

Journal of Electrocardiology, 1991
An improved method of calculating magnitude-squared coherence spectra on pairs of short-duration electrogram recordings is discussed. This method is based on adaptive signal processing techniques and yields spectra with higher resolution than those obtained using a straightforward direct method.
