Non-epileptic paroxysmal episodes: psychogenic hyperventilation crisis

The hyperventilation psychogenic Crisis (HPC) can appear as a sensation of shortness of breath, chest pain, palpitations, dizziness, headaches, numbness in the hands, and sometimes as a tetanus like state. For their classification they are included in non-epileptic paroxysmal episodes (NEPE). The patient interview and the clinical examination are the clues for the diagnosis and they prevent from unnecessary treatment and additional studies. The aim of this paper is to present two patients who consulted for NEPE secondary to HPC.
