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). 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. Kamagra oral Cheap viagra pills in uk SUDDEN DEATH AFTER IV METOPROLOL. ADMINISTRATION IN A PATIENT WITH CARDIOMYOPATHY.
