Exercise-induced right ventricular tachycardia and arrhythmogenic right ventricular dysplasia: electrophysiologic and therapeutic considerations

Texas Heart Institute Journal

Abstract

Three cases of exercise-induced ventricular tachycardia with associated right ventricular dysplasia are described. In each case, patients experienced ventricular tachycardia during treadmill tests. In all three patients, echocardiography or nuclear scintigraphy revealed a dilated right ventricle with reduced ejection fraction; cardiac catheterization with angiography also showed a dilated and hypokinetic right ventricle in each case. Two patients underwent electrophysiology studies that showed an inducible ventricular tachycardia originating from the right ventricular outflow tract. All three patients were treated with single agent antiarrhythmic drugs that controlled their ventricular tachycardia.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Arrhythmogenic Right Ventricular Dysplasia

Arrhythmogenic right ventricular dysplasia is a congenital cardiomyopathy that is characterized by infiltration of adipose and fibrous tissue into the right ventricle wall and loss of myocardial cells. Primary injuries usually are at the free wall of the right ventricular and right atria resulting in ventricular and supraventricular arrhythmias.
