Analyzed of heart rate variability and arrhythmia in Pulmonary Heart Disease

Objective To study the clinical significance of heart rate variability(HRV) and arrhythmia that have been detected by Holter in Pulmonary Heart Disease. Methods 21 Pulmonary Heart Disease was detected by physical examination, ECG and Holter. Results By Holter, 61.9% arrhythmia and 33.3% serious arrhythmia was detected in Pulmonary Heart Disease, that is higher than by physical examination and ECG. There is remarkable difference in these methods. In addition, SDNN, SDANN and SD that showed sympathetic tone in HRV of Pulmonary Heart Disease decreased as compared with the normal group. Conclusions Holter is good method in detecting arrhythmia of Pulmonary Heart Disease. It may be importance for treating serious arrhythmia of Pulmonary Heart Disease in clinical practice. The sympathetic tone increased when the SDAN SDANN and SD HRV of Pulmonary Heart Disease decreased. There is no relationship between HRV and arrhythmia in Pulmonary Heart Disease.
