Oral Bisoprolol Vs IV Diltiazem in Atrial Fibrillation or Flutter With Rapid Ventricular Rate.
Status: Not yet recruiting

INTRODUCTION: The study focuses on comparing the effectiveness of oral Bisoprolol, a beta-1 adrenergic receptor blocker, against intravenous Diltiazem, a calcium channel blocker, in treating rapid atrial fibrillation or flutter with rapid ventricular response in an emergency setting. This research aims to fill the gap in empirical evidence regarding the use of oral Bisoprolol for these conditions, potentially offering a convenient, evidence-based alternative for patient management in emergency departments where established protocols are lacking.

METHOD: This study is a randomized controlled trial targeting patients who present to the emergency room with symptomatic atrial fibrillation or flutter and rapid ventricular response requiring intervention. Participants will be split into two groups and undergo continuous monitoring of vital signs and regular electrocardiograms to ensure safety and document any adverse effects. The primary focus is on patient safety while evaluating the efficacy of the treatments.

AIM: Evaluate the efficacy and safety of oral bisoprolol in treating atrial fibrillation or atrial flutter with rapid ventricular response in an emergency department setting.

PRIMARY OJECTIVES: The primary efficacy outcome will be evaluated by achieving a HR<110 beats per minute or a decrease ≥20% of baseline HR at 60 minutes. The primary safety outcome measures are HR < 60 bpm and SBP < 95 mm Hg.

SECONDARY OBJECTIVES: The use of Rescue medication, proportion of patients who required hospitalization, worsening of heart failure or pulmonary oedema, side effect of medication ( dizziness, headaches, gastrointestinal symptoms)

PATEINT POPULATION: Adults (18 and older) presenting to the emergency department at Sultan Qaboos University Hospital with symptomatic atrial fibrillation or atrial flutter with rapid ventricular response requiring treatment.

INTERVENTION: A single oral dose of 5 mg Bisoprolol (maximum dose of 5 mg) or a single intravenous dose of Diltiazem at 0.25 mg/kg (to a maximum dose of 30 mg).

CLINICAL MEASURMENT: Heart rate recorded every 15 minutes up to the 90-minute mark, with a 12-lead ECG performed every 30 minutes.

OUTCOME: For therapy to be considered effective, patients must achieve a ventricular rate ≤110/min or experience a drop-in ventricular rate of at least 20% at 60 minutes.
