GLP-1 receptor agonists do not significantly increase the overall risk of cardiac arrhythmias (atrial fibrillation, atrial flutter, ventricular arrhythmias, or sudden cardiac death) in patients with type 2 diabetes or obesity compared to controls.

For patients with Type 2 Diabetes or Obesity, GLP-1 medications (like Ozempic, Trulicity, or Wegovy) are generally safe regarding heart rhythm. While they may slightly increase your resting heart rate, large studies show they do not increase the risk of serious heart rhythm problems like atrial fibrillation or ventricular arrhythmias compared to other treatments. However, those with very high BMI or on high doses should be monitored for ventricular arrhythmias.

GLP-1 RAs use overall did not significantly increase the risk of AF (RR 0.97, 95% CI 0.83–1.12), AFL (RR 0.83, 95% CI 0.59–1.17), VAs (RR 1.24, 95% CI 0.92–1.67), and SCD (RR 0.89, 95% CI 0.67–1.19), compared with controls.
