Analysis of 24-Hour Heart Rate Variability among Panic Disorder Patients without Previous Drug Treatment and Comorbid Disorders.

Objective: One of the METHODS used to assess autonomic nervous system dysfunction in the etiology of panic disorder (PD) is heart rate variability (HRV). HRV is controlled by the sympathetic and parasympathetic (vagal) branches of the autonomic nervous system and reflects the capacity of autonomic stimulation by the parasympathetic system. The aim of this study was to evaluate heart rate variability (HRV) time domain parameters based on twenty four hour holter ECG analysis among drug-naive patients with panic disorder (PD) without any other medical and psychiatric comorbidity.

Treatment Approach to Sleep Terror: Two Case Reports.

Parasomnias are a group of disorders characterized by abnormal behaviors, physical activities, and autonomic arousal symptoms while transition to sleep or continuation of sleep. Sleep terror (ST) is classified under parasomnias characterized by sudden fear attacks beginning with crying attacks or high-frequency screams and continuing with increased autonomic symptoms. ST occurs in the first few hours of sleep during the delta phase.
