Value of Heart Rate Variability in Diagnosis and Treatment of Schizophrenia
As one of the severe mental illnesses in the world,schizophrenia has a high mortality rate and high comorbidity rate,which has caused a huge economic burden to the world.Therefore,early intervention for schizophrenia is crucial.Heart rate variability(HRV),a non-invasive heart monitoring technology commonly used in cardiology departments,reflects the steady-state changes of the body's autonomic nervous system and can be used to evaluate the patient's current physical status and heart function.Studies have shown that for patients with schizophrenia,their heart rate variability is generally lower than that of normal people,which may be related to the severity of psychiatric symptoms.In addition,adequate doses of antipsychotic drugs may also alter the patient's autonomic homeostasis,thereby affecting the patient's cardiac function.In short,heart rate variability can be used as a quantitative indicator of schizophrenia and plays a role in many aspects such as assessing autonomic nervous function and monitoring drug toxicity in patients with schizophrenia.This article provides an overview of HRV and schizophrenia,and discusses the influencing factors of HRV,the imbalance of autonomic nervous function in patients with schizophrenia,the relationship between HRV and the psychiatric symptoms of schizophrenia,and the correlation between HRV and schizophrenia treatment plans.This paper prompts that HRV can be used as a quantitative characteristic and biological indicator for the evaluation of autonomic nervous function in patients with schizophrenia.
