Clinical Trial Summary

The goal of this observational study is to investigate ventricular repolarization utilizing Tp-e intervals and Tp-e/QT ratios in patients with DM. The main questions it aims to answer are:

• 1.Exploring the changes in ventricular repolarization parameters (QT interval, QTc interval, QTd, Tp-e interval, Tp-e/QT ratio) in patients with dermatomyositis, providing quantifiable indicators for early detection of arrhythmia in dermatomyositis patients;

• 2.Exploring the role of inflammation in ventricular repolarization in DM patients, providing a basis for in-depth research on the diagnosis and prevention of arrhythmia in DM patients.
