• Focal AT is defined as an organized atrial rhythm ≥100 b.p.m. initiated from a discrete origin and spreading over both atria in a centrifugal pattern.
• Beta-blockers (i.v. esmolol or metoprolol) should be considered in the absence of decompensated HF, if adenosine fails.
• Verapamil or diltiazem (i.v.) should be considered for haemodynamically stable patients in the absence of hypotension or HFrEF, if adenosine fails.
• In general, acute therapy may be initiated with beta-blockers or calcium channel blockers, which may terminate focal ATs or slow the ventricular rate (Figure 8).
