By Najm Haque, PGY2 Atrial fibrillation with rapid ventricular response is a common emergency room problem. Patient with stable blood pressure who present in Afib with RVR need medications to control their heart rate (unstable patients require more cardioversion). Traditionally, these patients receive beta blockers or calcium channel blockers in IV form for rate control. The most common medications used in the US are metoprolol and diltiazem, but it is unclear which is superior. Fromm et al This study was published in the Journal of Emergency Medicine in April 2015 and compared how fast rate control was achieved in diltiazem vs metoprolol. This was a prospective, double-blind study which compared the effects of both medications at 30 minutes, as well as looking at mean decrease in heart rate, and adverse effects. Patients were randomized and either received Diltiazem 0.25 mg/kg IVP (maximum dose of 30mg) or Metoprolol 0.15mg/kg IVP (maximum dose of 10mg). zoloft generic Abrupt cessation my precipitate angina, MI, arrhythmias, or rebound HTN; discontinue by tapering over 1-2 weeks. Immediate-release form is metoprolol tartrate; extended-release form is metoprolol succinate. When switching from immediate release to extended-release product, use same total daily dose. The immediate and extended release products may not give same clinical response on mg:mg basis; monitor response and side effects when interchanging between metoprolol products. Concomitant amiodarone, digoxin, disopyramide, or non-dihydropyridine calcium channel blockers may increase the risk of bradycardia. Monitor closely for HF exacerbation and hypotension when titrating dose.

METOPROLOL TARTRATE: Early Treatment: Initial dose: 5 mg IV every 2 minutes as tolerated for 3 doses -Patients tolerant of full IV dose (15 mg): 50 mg orally every 6 hours starting 15 minutes after the last IV dose and continued for 48 hours -Patients intolerant of full IV dose (15 mg): 25 or 50 mg orally every 6 hours depending on the degree of intolerance starting 15 minutes after the last IV dose or as soon as their clinical condition allows Late Treatment: Maintenance dose: 100 mg orally twice a day Comments: -Patients with contraindications to treatment during the early phase of suspected or definite myocardial infarction, patients who appear not to tolerate the full early treatment, and patients in whom the physician wishes to delay therapy for any other reason should be started on 100 mg orally twice a day as soon as their clinical condition allows. -Continue therapy for at least 3 months; efficacy beyond 3 months has not been conclusively established; data from studies with other beta blockers suggest a treatment duration of 1 to 3 years. Use: Treatment of hemodynamically stable patients with definite or suspected acute myocardial infarction to reduce cardiovascular mortality. Treatment with the IV formulation can be initiated as soon as the patient's clinical condition allows. Alternatively, treatment can begin within 3 to 10 days of the acute event.
