GPT and cardiac rhythm disease: Even after adjusting for factors such as age, primiparity, BMI, hypertension, systolic blood pressure and diastolic blood pressure, aspartate aminotransferase, alanine aminotransferase, fasting blood glucose, and total cholesterol, the correlation between a history of cardiac arrhythmia and GDM remained statistically significant (adjusted OR, 1.78; 95% CI, 1.61 to 1.97; p< 0.001; Figure 1).
