CACAF involved 137 patients with paroxysmal or persistent AF refractory to two or more different antiarrhythmic agents who were randomized to catheter ablation plus antiarrhythmic drug
therapy or antiarrhythmic drug
And while ablation may not have the side effects of antiarrhythmic drugs
, the procedure carries a small risk of bleeding and stroke (about 1 percent), Dr.
Kowey, who has served as a consultant to numerous pharmaceutical companies interested in developing antiarrhythmic drugs
Physicians tend to think of ablation and antiarrhythmic drug
therapy as separate treatments, but "there can be synergies between the two," Dr.
Section One comprehensively reviews basic cardiac electrophysiology, the mechanisms responsible for arrhythmias in the setting of ischemia, and basic pharmacology of antiarrhythmic drugs
This is a far more attractive option than dithering around with one antiarrhythmic drug
For those patients who had reached six months, 7/7 (100%) patients experienced normal sinus rhythm without antiarrhythmic drugs
This agent acts by blocking both rapid and slow potassium channels in myocardium, and is chemically distinct from other class III antiarrhythmic drugs
like sotalol, amiodarone, and dofetilide.
Implantable cardioverter-defibrillators are more effective than antiarrhythmic drugs
in preventing arrhythmic cardiac death, but they do not affect rates of death from other cardiac causes.
A diagnosis of atrial fibrillation is usually followed by a course of treatment involving antiarrhythmic drugs
designed to keep the heart's electrical system under control.
BOSTON -- Catheter ablation is superior to an assortment of antiarrhythmic drugs
in the treatment of patients with paroxysmal atrial fibrillation who have previously failed at least one AAD, according to a new study.
American Heart Association guidelines call antiarrhythmic drugs
"acceptable, probably helpful" for ventricular fibrillation or pulseless ventricular tachycardia that persists after three or more shocks from an external defibrillator.
