Instantaneous Heart Rate Variability(HRV) Signal Cloud Portable Flat Panel Observation

This study is an instantaneous heart rate variability (HRV) signal cloud portable flat panel observation. HRV applications reflect the heart and cardiovascular disease. Patients with essential hypertension and myocardial infarction, vagal decay are reflected in the heart rate variability. Heart rate variability is also used as a predictor. Neurology, heart rate variability can reflect a variety of central nervous autonomic disorders. Such as Parkinson's disease, chronic alcoholism, limb paralysis and so on. Cardiomyopathy caused by diabetes mellitus and diabetes mellitus will reduce heart rate variability. The decrease in heart rate variability is before the onset of clinical conditions.
