How can arrhythmia be treated?
Treatment for heart arrhythmias may include medications, therapies such as vagal maneuvers, cardioversion, catheter procedures or heart surgery….Pacemakers, defibrillator
- Catheter ablation.
- Pacemaker.
- Implantable cardioverter-defibrillator (ICD).
- Maze procedure.
- Coronary bypass surgery.
What is the pathophysiology of arrhythmia?
Pathophysiology of Arrhythmias. Rhythm disturbances result from abnormalities of impulse formation, impulse conduction, or both. Bradyarrhythmias result from decreased intrinsic pacemaker function or blocks in conduction, principally within the AV node or the His-Purkinje system.
What is the drug of choice for arrhythmia?
Encainide, tocainide, and mexiletine are effective in treating acute and chronic ventricular arrhythmias. Verapamil promises to be the drug of choice for paroxysmal supraventricular tachycardia.
What is the best medication for arrhythmia?
Flecainide, sotalol (also a beta blocker) and amiodarone are also commonly prescribed for arrhythmias. They have the ability to terminate an arrhythmia and are usually given to prevent the abnormal rhythm from occurring or reduce its frequency or duration.
What is the main cause of arrhythmia?
The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heart beat. Many factors can affect your heart’s rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress. Some substances or medicines may also cause arrhythmias.
What is the physiology of atrial fibrillation?
During atrial fibrillation, the heart’s upper chambers (the atria) beat chaotically and irregularly — out of sync with the lower chambers (the ventricles) of the heart. For many people, A-fib may have no symptoms. However, A-fib may cause a fast, pounding heartbeat (palpitations), shortness of breath or weakness.
What is the mechanism behind atrial fibrillation?
AF is a complex disease that is fueled by the structural alterations (substrate) in the atria that consequently result in complex electrophysiological defects and patterns that render the atria and autonomic system dysfunctional, which then lead to a vicious cycle of exacerbated atrial and ventricular remodeling events …
What causes atrial fibrillation and right ventricular arrhythmia?
Nevertheless, growing evidence suggests that both atrial fibrillation and right ventricular arrhythmia can be caused by intense exercise in some individuals. Exercise-induced atrial fibrillation is most commonly diagnosed in middle-a …
What can cardiac ablation do for exercise induced arrhythmia?
Cardiac ablation is evolving as a first-line tool for athletes with exercise-induced arrhythmia who are eager to remain active.
Which is the most common type of cardiac arrhythmia?
Atrial fibrillation (AF) is the most frequently encountered sustained cardiac arrhythmia in clinical practice and a major cause of morbidity and mortality. Effective treatment of AF still remains an unmet medical need. Treatment of AF is based on drug therapy and ablative strategies.
Which is the most common diagnosis of exercise induced atrial fibrillation?
Exercise-induced atrial fibrillation is most commonly diagnosed in middle-a … Diagnosis, pathophysiology, and management of exercise-induced arrhythmias Nat Rev Cardiol. 2017 Feb;14(2):88-101.doi: 10.1038/nrcardio.2016.173. Epub 2016 Nov 10. Authors Eduard Guasch 1 , Lluís Mont 1
