Can isolated, symptomatic, frequent ventricular premature depolarizations be a predictor of an inducible ventricular tachycardia? Treatment by radiofrequency catheter ablation

Abstract

In this report, we describe a case of sustained ventricular tachycardia of right ventricular outflow tract origin, induced by dobutamine infusion in a patient with symptomatic, frequent ventricular premature depolarizations but no documented clinical ventricular tachycardia. Radiofrequency catheter ablation abolished not only the ventricular tachycardia itself, but also the frequent ventricular premature depolarizations responsible for all the symptomatology. In conclusion, provocation by catecholamine infusion may have a place in the search for an alternative to antiarrhythmic therapy in patients with isolated, frequent and symptomatic ventricular premature depolarizations.

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.

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.

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.
