Role of IV Calcium to Prevent Diltiazem-related Hypotension

Summary

The objective of this study is to examine the efficacy and safety of IV calcium pretreatment at varying doses prior to weight-adjusted IV Diltiazem on the incidence of Diltiazem-related hypotension in adult patients presenting to the Emergency Department due to Atrial Fibrillation with Rapid Ventricular Response. Specifically, we tested the hypothesis that patients with Atrial Fibrillation who receive IV calcium pretreatment prior to IV Diltiazem suffer less hypotension than those receiving Diltiazem monotherapy.
