Summary
•In view of his advanced age and risk factors, Santa Claus is at high risk of developing atrial fibrillation. Despite this, no guidelines exist on the subject.
•Following a review of the literature, we present our position on the management of atrial fibrillation in Santa Claus, and propose the use of the SANTA CLAUS mnemonic to aid clinicians: Screen for atrial fibrillation; Anticoagulate; Normalise heart rate; Treat comorbidities; Anti‐arrhythmic drugs; Cardioversion; Lifestyle measures; Ablation treatment; Understand emotional and psychological impact; Save Santa Claus.
