Background Sacubitril/valsartan (SacVal) has been shown to improve the prognosis of heart failure; however, whether SacVal reduces the occurrence of atrial fibrillation (AF) in heart failure has not yet been elucidated. SacVal attenuated the increased heterogeneity of CV at short pacing cycle length in atria, whereas Val could not.

An atrial fibrillation (AF) model was created with isoproterenol and acetylcholine. In the presence of pinacidil induced arrhythmogenicity, neither SGLT2 inhibitor had a significant impact on cardiac electrophysiology. Conclusion In this model, empagliflozin and dapagliflozin demonstrated opposite antiarrhythmic properties.
