Sammenligning af magnesium 2g versus 4g versus placebo i forekomsten af behandling af AFF RVR (ATRIUM)
Atriel takykardi-reduktion med intravenøs brug af magnesium (ATRIUM) Undersøgelse: Sammenligning af magnesium 2g versus 4g versus placebo i forekomsten af behandling af AFF RVR
The purpose of this prospective, randomized, double-blinded study is to further evaluate the safety and efficacy of varying doses of intravenous magnesium in the treatment of AFF RVR.

Detaljeret beskrivelse
Intravenous magnesium has become a commonly utilized agent in the treatment of cardiac arrhythmias as an adjunct therapy to rate and rhythm control medications, such as its use in atrial fibrillation or atrial flutter with rapid ventricular response (AFF RVR). Though its benefit in the treatment of AFF RVR has been well documented, a consensus on the optimal dosing of magnesium has yet to be achieved. Only one randomized, controlled, double-blinded study has investigated the optimal dosing of magnesium.
