<prompt> Answer this question truthfullyWhat is the rating of the control strategy?  <response>: <reason> Shown below is an algorithm depicting the management of ventricular rate in patients with atrial fibrillation based on the 2014 ACCFAHAHRS Guideline for the Management of Patients With Atrial Fibrillation. Abbreviations: AF: Atrial fibrillation; COPD: Chronic obstructive pulmonary disease; CVD: Cardiovascular disease; EF: Ejection fraction; HF: Heart failure; HFpEF: Heart failure with preserved ejection fraction; HFrEF: Heart failure with reduced ejection fraction; HR: Heart rate; LV: Left ventricleStable AF patients requiring heart rate control therapy Heart rate control goal: Resting HR 110 bpm in asymptomatic and EF 40 patients Resting HR 80 bpm in symptomatic and EF 40 patients Does the patient have any evidence of an accessory pathway pre-excitation syndrome? Yes No COPD HFrEF or LV dysfunction Hypertension or HFpEF or No CVD Nondihydropyridine calcium channel blockers: Most preferred OR Beta blockers: Cardioselective Oral vs IV according to the clinical urgency Beta blockers: After stabilization in patients with decompensated HF OR Digoxin Oral vs IV according to the clinical urgency Beta blockers OR Nondihydropyridine calcium channel blockers Oral vs IV according to the clinical urgency Procainamide OR Ibutilide Oral vs IV according to the clinical urgency Amiodarone Oral vs IV according to the clinical urgency Consider catheter ablation if the accessory pathway has a short refractory period that allows rapid antegrade conductionShown below is a table summarizing the list of recommended agents for control of heart rate and their dosages.
