Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of intravenous diltiazem and verapamil for the acute treatment of atrial fibrillation and atrial flutter.
To compare the efficacy and safety of intravenous diltiazem and verapamil in controlling ventricular rate in patients with atrial fibrillation or flutter, and to evaluate the effects of these agents on left ventricular systolic function. ⋯ Intravenous diltiazem and verapamil are comparable in terms of efficacy and effect on systolic function in patients with rapid atrial fibrillation and flutter. However, hypotension may limit therapy with verapamil in some patients.
