IV Potassium and Magnesium an Acute Treatment for AF?
The probability of spontaneous conversion to sinus rhythm (SVC) was increased with the intravenous administration of magnesium and potassium in patients with nonpermanent atrial fibrillation presenting to the ER, a new registry study shows. Compared with no treatment, potassium and magnesium administration was associated with a 10% higher rate of SVC. The finding suggests that giving intravenous potassium and magnesium might lessen the need for antiarrhythmic therapy and the associated potential adverse effects in patients with nonpermanent atrial fibrillation, the study authors say.

Each intervention has specific risks, and neither is considered cost-effective owing to frequent recurrence of AF. In addition, AF often terminates spontaneously
