Atrial Fibrillation, Atrial Flutter
Conditions
Brief summary
The primary objective of the study is to reduce hospital admission and decrease time to disposition through establishing an effective treatment protocol for AF and Atrial Flutter in the Emergency Department of Spectrum Health Lakeland. Secondary outcome is to measure if oral diltiazem is an effective HR controlling agent in AF RVR and Flutter.
Interventions
Diltiazem 0.25mg/kg injection, give over 2 minutes, max dose 30mg
these patients will receive traditional treatments at provider discretion. They must receive at least one intravenous medication for atrial fibrillation with rapid ventricular response. This will be a heterogenous group of patients receiving digoxin, amiodarone, various beta-blockers, and intravenous diltiazem without oral diltiazem.

Study design
Intervention model description
A treatment protocol using oral and IV diltiazem has been implemented. We will compare admission rates, time to heart rate control, and hypotension between the protocol group and patients receiving traditional treatments for atrial fibrillation with rapid ventricular response

| Diltiazem With Oral and Intravenous Treatment Diltiazem 0.25mg/kg injection, give over 2 minutes, max dose 30mg. 15 minutes following Diltiazem Infusion administer oral Diltiazem 60mg IR Tablet, do not give if BP\<100
Oral: Diltiazem 0.25mg/kg injection, give over 2 minutes, max dose 30mg | 177 |
| Traditional Atrial Fibrillation With Rapid Ventricular Response these patients will receive traditional treatments at provider discretion. To be included in teh study their initial heart rate must also be over 125, and they must receive at least one intravenous medication for atrial fibrillation with rapid ventricular response. This will be a heterogenous group of patients receiving digoxin, amiodarone, various beta-blockers, and intravenous diltiazem without oral diltiazem.
Intravenous drug: these patients will receive traditional treatments at provider discretion. They must receive at least one intravenous medication for atrial fibrillation with rapid ventricular response. This will be a heterogenous group of patients receiving digoxin, amiodarone, various beta-blockers, and intravenous diltiazem without oral diltiazem. | 267 |
