Brief summary
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.

| heart failure and sleep apnea | 24 hours | 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. Collection of clinical data: general clinical data, physical signs, post-admission inspection indicators, and treatment conditions of patients collected from the electronic medical record system. Echocardiographic data mainly included ejection fraction, left atrial anterior-posterior diameter, and interventricular septum thickness, which were in millimeters; electrocardiogram examination mainly included Diagnosis type of arrhythmia by dynamic, the overall standard deviation of normal sinus R-R interval (SDNN), the average standard deviation of normal sinus R-R interval throughout the recording period (SDANN), which were in a millisecond, etc; The type and severity of sleep-disordered breathing and Apnea hypopnea index were obtained by polysomnography. |
