Evaluation of Tp-e Interval and Tp-e/QT Ratio in Dermatomyositis and Analysis of Their Relationship With Inflammation
Study Details
Study Description
Brief 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.

Outcome Measures
Primary Outcome Measures
- QTc, Tp-e interval, and Tp-e/QT ratio were increased in DM patients. [January 2017 to October 2022]
- the Tp-e interval and Tp-e/QT ratio were positively correlated with Inflammation. [January 2017 to October 2022]
