NCT05550441

Brief Summary

This project plans to design a randomized controlled clinical trial to evaluate the effect of dapagliflozin on ventricular arrhythmia in the participants with heart failure with reduced ejection fraction after ICD implantation by collecting and analyzing the data of ECG, cardiac ultrasound and ICD programming. This project will explore the anti-ventricular arrhythmia effect of dapagliflozin in HFrEF patients.
