Study Overview
Brief Summary
This is a prospective, open labelled, randomised control trial of parallel group to compare the effects of intravenous Metoprolol versus Diltiazem in controlling heart rate in hemodynamically stable patients presenting to Emergency department with ECG features suggestive of Atrial Fibrillatiion with fast ventricular rate.Patients more than or equal to 18 years with an ECG evidence of fibrillation with heart rate more than 110 are included in the study after excluding patients meeting excluding criteria.Then patient will be randomised in two different arm based on block randomisation using computer generated sequences and allocation concealment will be done. Primary objective is to compare the effects of Metoprolol v/s Diltiazem in decreasing heart rate to less than 110 bpm or 20% reduction of initial heart rate within 30 minutes of drug administration, secondary objectives would be to evaluate the incidence of hypotension, bradycardia and requirement of second dose of same medication or subsequent doses of other class of medications for rate control and length of hospital stay in such patients.

Outcomes
Primary Outcomes
To compare the effects of Metoprolol versus Diltiazem in decreasing heart rate to less than 110 beats per minute or 20% reduction of initial heart rate within 30 minutes of drug intake
Time Frame: The outcome of drug intake are estimated after 30 minutes.
Secondary Outcomes
- To evaluate the incidence of hypotension(systolic blood pressure to less than 90 mm of mercury) and bradycardia (heart rate less than 60 beats per minute)(within 30 minutes of drug administration)
- To evaluate the incidence of requirement of second dose of same medication or subsequent doses of other class medication for rate control(Within 30 minutes of drug administration)
- To evaluate the incidence of length of ED stay(Within 30 minutes of drug administration)
