Purpose:
To explore the state of mental treatment, heart rate variability (HRV), level of aggressive behavior, and their relationships among hospitalized patients with schizophrenia.
Design And Methods:
This study adopted a follow-up design and convenience sampling. Thirty-three subjects completed the questionnaire, and their HRV indices were measured.
Findings:
Patients' psychiatric symptoms showed a significant downward trend after hospitalization (P = .003). The standard deviation of the normal-to-normal intervals in the morning was significantly correlated with overall aggression, physical aggression, and verbal aggression.
Practice Implications:
HRV can be regularly monitored among inpatients with schizophrenia with a risk of high aggression as an indicator of possible aggressive behavior.

Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...
