About this trial
The purpose of this research study is to find out if the use of magnesium in addition to Metoprolol, a rate controlling medication that you would be offered in the Emergency Department today unrelated to this study, will help reduce your high heart rate (rapid ventricular response).
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age > 18 years or older
Able to provide informed consent
Primary diagnosis atrial fibrillation or atrial flutter with rapid ventricular response (AFF RVR) greater than or equal to 120 beats per minute
Metoprolol as rate control agent
Disqualifiers
Hemodynamically unstable patients (SBP <90, MAP <65)
Impaired consciousness
Acute heart failure exacerbation based on clinical diagnosis, physician exam, bedside echo, and/or additional imaging
Patient in AFF RVR that is highly suspected to be a compensatory mechanism for an alternative clinical diagnosis
Trial design
