About

The purpose of this study is to analyze and summarize the characteristics of arrhythmia and heart rate variability of Chinese patients with three different types of heart failure combined with sleep disordered breathing based on the clinical data, to provide new diagnosis and treatment ideas for domestic patients, and then to improve the prognosis of patients betterly.
