노인 뇌졸중 환자의 24시간 심박변동 분석을 이용한 자율 신경 기능 분석

Abstract

Background: Impaired autonomic function is common in the acute poststroke phase but little is known about autonomic function in the geriatric stroke survivor. We wanted to determine if autonomic function is impaired after stroke recovery in older patients.

Methods: 24-hour heart rate variability (HRV) analysis was performed for 20 ischemic stroke patients older than 65 years old and 20 control subjects older than 65 years old.

Results: Geriatric stroke patients had lower parameters of time domain and power spectrum of HRV compared with control. There was no significant difference of HRV between right and left hemiplegic subjects. Quadriplegic subjects had lower parameters of time domain and power spectrum of HRV compared with hemiplegic subjects.

Conclusion: Cardiovascular autonomic function is impaired in old aged stroke survivors.
