BACKGROUND: Many authors suggest that there is low reactivity of autonomic nervous system and reduced heart rate variability in patients with panic disorder. The patients are therefore exposed to increased cardiac mortality. Power spectral analysis is a successful tool in detecting autonomic instabilities in many disorders.
SUBJECTS AND METHODS: The aim of our study is to monitor the activity of the autonomic nervous system through heart rate variability measured in the beginning and end of a therapeutic cognitive behavioral therapy (CBT) program in patients with panic disorder. We measured 31 patients with panic disorder in the beginning (1st measurement) and end of a therapeutic CBT program (2nd measurement). The autonomic nervous system (ANS) has been evaluated in three positions (supine - standing - supine). The evaluated parameters of the HRV linear analysis were: RR interval, HF, LF, VLF band and VLF + LF / HF ratio.
RESULTS: Spectral activity in the very low frequency band was significantly higher in the 2nd measurement compared to the 1st measurement in the standing position. The ratio of the spectral activity at lower frequencies (VLF+LF) to high frequency (HF) was significantly lower in the supine position.
CONCLUSION: This study demonstrated an improvement of neurocardiac control regulation after a therapeutic CBT program in patients suffering from panic disorder.
