Blood Pressure Drop Prediction by using HRV Measurements in Orthostatic Hypotension

摘要: Orthostatic Hypotension is defined as a reduction of systolic and diastolic blood pressure within 3 minutes standing, may cause dizziness loss balance. has been considered an important risk factor for falls since 1960. This paper presents model to predict the drop due orthostatic hypotension, relying on heart rate variability measurements extracted from 5 minute ECGs recorded before standing. was developed validated with leave-one-out cross-validation technique involving 10 healthy subjects, finally tested additional whose data were not used during training process. The results show that predicts correctly in 80 % all experiments, error below measurement sphygmomanometer digital device.
