Heart Rate Variability and Orthostatic Hypotension in Stroke Patients Evaluated by Intelligent Biosensor System

Heart Rate Variability and Orthostatic Hypotension in Stroke Patients Evaluated by Intelligent Biosensor System

This research investigated the heart rate variability (HRV) and stroke patients' orthostatic hypotension in hospitalized stroke patients accompanied with dizziness at varied tilting angle controlled by tilting table with intelligent biosensor.

Stroke patients readily accompany with the occurrence of orthostatic hypotension. To earlier predict patients occurring dizziness during the tilt table test, this study utilized a self-developed integrated intelligent biosensor system to assist clinical staff efficiently and immediately assessing stroke patients with orthostatic hypotension. Further purposes were to survey the relationship between the orthostatic hypotension and heart rate variability (HRV) and find the predicted models of orthostatic hypotension.

Inclusion Criteria:

• Patients who are first time to get stroke.

Exclusion Criteria:

• unstable physiological conditions, serious joint spasticity, use cortisol or calming drugs, other neurological diseases
