Psychiatry Res. 2008 Jan 15;157(1-3):307-10. doi: 10.1016/j.psychres.2007.07.015. Epub 2007 Oct 26.

Abstract

In this study 117 panic disorder patients were divided into a respiratory subtype group and a non-respiratory subtype group. The respiratory subtype patients were observed to be more sensitive to the 35% CO(2) inhalation challenge test and the hyperventilation test than the non-respiratory subtype patients.
