  1. 01HumanSystematic reviewSafety outcome

    In adults with overweight or obesity, tirzepatide was not significantly associated with atrial fibrillation versus placebo (pooled OR 2.20, 95% CrI 0.81-6.75).

    In plain wordsIn adults with overweight or obesity, tirzepatide was not clearly linked to more atrial fibrillation than placebo.

  3. 03HumanSystematic reviewSafety outcome

    In adults with overweight or obesity, tirzepatide was associated with higher odds of any arrhythmia versus placebo (pooled OR 1.84, 95% CrI 1.04-3.90).

    In plain wordsIn adults with overweight or obesity, tirzepatide was linked to higher odds of any heart rhythm problem than placebo, though event rates were low.
