Study facts come from the paper. Population match, weight-loss explanation and study tier are our judgments, made against the reference group of healthy normal-weight adults aged 55–75.
[Auto, unreviewed; quoted from abstract conclusions] Tirzepatide was not associated with atrial fibrillation or atrial arrhythmia. Although higher odds of overall arrhythmias were observed, event rates were low and the findings should be interpreted cautiously.

Abstract
[BACKGROUND] Tirzepatide is a dual agonist for glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptors, with proven efficacy in weight loss and improvement in cardiovascular outcomes. However, the effects of tirzepatide on the incidence of atrial fibrillation in patients with overweight or obesity remain unclear. [METHODS] PubMed, Embase, and Cochrane Library were searched for randomized controlled trials comparing tirzepatide versus placebo for individuals with overweight or obesity. Odds ratios (ORs) with 95% credible intervals (CrIs) were pooled using a Bayesian binomial-normal hierarchical model, appropriate for rare-event outcomes. [RESULTS] Our meta-analysis included 10 randomized controlled trials, including 6515 individuals, of whom 4491 (68.9%) were randomized to tirzepatide. The pooled OR was 2.20 (95% CrI, 0.81-6.75) for atrial fibrillation, 2.16 (95% CrI, 0.90-5.87) for atrial arrhythmia, and 1.84 (95% CrI, 1.04-3.90) for any arrhythmia. [CONCLUSIONS] Tirzepatide was not associated with atrial fibrillation or atrial arrhythmia. Although higher odds of overall arrhythmias were observed, event rates were low and the findings should be interpreted cautiously.
