Treatment of First-Diagnosed Atrial Fibrillation in Haemodynamically Stable Patients
This protocol applies to patients presenting with atrial fibrillation for the first time — no prior AF diagnosis, regardless of symptom status, temporal pattern, or duration — who remain haemodynamically stable at presentation.
Clinical scenario
First-diagnosed AF in a haemodynamically stable patient. The absence of haemodynamic compromise allows for a systematic, evidence-based initial approach rather than emergency intervention.
Treatment target
A resting heart rate below 110 b.p.m. is the initial target (lenient rate control). Stricter control is reserved for patients who continue to experience AF-related symptoms despite achieving this threshold.
Approach (partial overview)
Initial management is centred on rate control therapy using a single pharmacological agent. The selection of that agent is guided by left ventricular ejection fraction — the full evidence-based regimen specifies which agents are appropriate for each functional category.

- AF that has not been diagnosed before, regardless of symptom status, temporal pattern, or duration.
- Rate control therapy is recommended in patients with AF, as initial therapy in the acute setting, an adjunct to rhythm control therapies, or as a sole treatment strategy to control heart rate and reduce symptoms.
- Beta-blockers and/or digoxin are recommended in patients with AF and LVEF ≤40% to control heart rate and reduce symptoms.
- Beta-blockers, diltiazem, verapamil, or digoxin are recommended as first-choice drugs in patients with AF and LVEF >40% to control heart rate and reduce symptoms.
- Lenient rate control with a resting heart rate of <110 b.p.m. should be considered as the initial target for patients with AF, with stricter control reserved for those with continuing AF-related symptoms.
