Key result
IV metoprolol controls ventricular rate in ~81% of patients with supraventricular tachyarrhythmias.
Why the study?
The efficacy of intravenously administered metoprolol in controlling ventricular rate in supraventricular tachyarrhythmias was evaluated.
Does intravenously administered metoprolol reduce ventricular rate in patients with supraventricular tachyarrhythmias?
Does intravenously administered metoprolol reduce ventricular rate in patients with supraventricular tachyarrhythmias?
Intravenous metoprolol is rapidly effective in controlling ventricular rate in patients with supraventricular tachyarrhythmias, though transient hypotension is a common side effect.

IV metoprolol evaluated in 16 SVT patients; leaves open its efficacy and role in practice.
Amsterdam et al. (1991) studied Supraventricular tachyarrhythmias (n=16). Intravenously administered metoprolol was evaluated on Response (control of ventricular rate). Intravenous metoprolol effectively controlled ventricular rate in 81% of patients with supraventricular tachyarrhythmias, reducing mean rate from 134 to 106 beats/min at 10 minutes.
