| Author, Year | Design or Sample Size | Intervention & Comparison | Outcome |
| Kuang, 2016 | Retrospective (n=398) | BB naïve patients vs patients on chronic BB therapy | -BB naïve patients achieved successful rate control at higher rates |
| Martindale, 2015 | Systematic
review (n=92) |
Diltiazem vs Metropolol | -Diltiazem is more effective at rapidly controlling ventricular rates |
| Fromm, 2015 | Prospective,
randomized, double blind (n=52) |
Diltiazem 0.25 mg/kg (max 30mg) vs Metropolol 0.15 mg/kg (max 10mg) | -Diltiazem decreased heart rate more rapidly and substantially within first 30min |
| Scheuermeyer,
2013 |
Retrospective (n=259) | CCB (Diltiazem or Verapamil) vs BB (Metropolol or Atenolol) | –No difference in admission rates, length of stay, adverse events, and 7 or 30-day ED revisits |

Prospective,
randomized (n=40) |
Diltiazem 0.25mg/kg (max 25mg) Metoprolol 0.15mg/kg (max 10mg) | -Successful rate control was similar at 20 minutes |
