Dyspnea during panic attacks. An Internet survey of incidences of changes in breathing.

This article presents the results of a survey that investigated breathing-related symptoms of panic attacks together with the frequency of other symptoms reported by active panickers. All the participants of this study experienced naturally occurring panic attacks and sought treatment guidance by visiting a Web site devoted to the treatment of panic. The results of a symptom questionnaire showed that 195 respondents (95.1%) reported breathing changes during panic attacks, and remarkable dyspnea was reported by more than two thirds (68%) of respondents. These findings are consistent with earlier studies but are contrary to conclusions that only a small number of panickers report shortness of breath as a symptom. This study concludes that outside of the laboratory, a large majority of people who suffer from panic attacks experience symptoms of dyspnea.
