Podcast 773: Atrial Fibrillation Medications

Contributor: Aaron Lessen, MD

Educational Pearls:

  • Atrial fibrillation is an irregular heart rhythm that sometimes requires rate control in setting of rapid ventricular response (RVR)
  • Calcium channel blocker and beta blockers are the most frequently used medications to block the AV node and slow down the heart rate in atrial fibrillation with RVR
  • If a patient is on one of these agents at home, the IV form should be used first
  • Recent systematic review and meta-analysis found 3 trials addressing which medication to use to control heart rate in atrial fibrillation with RVR with a total of 150 patients
  • Found diltiazem, a CCB, was 4x more likely to reduce heart rate than metoprolol
  • 50% of patients had a normal heart rate at 21 minutes with diltiazem versus 22% in those who received metoprolol
  • Both agents had a similar decrease in blood pressure after administration
