For ECG characteristics, between baseline and follow-up, there were minute increases in PR interval, QT prolongation by Bazett's formula, and QT prolongation by Fridericia's formula in both SGLT2 inhibitor group and non-SGLT2 inhibitors group that may be related to diabetic cardiomyopathy, albeit not clinically relevant. The gene discussed is SLC5A2; the disease is diabetic cardiomyopathy.
