Supports first-line IV verapamil for acute SVT termination; confirms high efficacy versus placebo in re-entrant tachycardias.
Does intravenous verapamil improve conversion to sinus rhythm in patients with sustained supraventricular tachycardia?
Intravenous verapamil is highly effective for terminating re-entrant supraventricular tachycardias, primarily through its depressive action on the AV node.
