Hyperventilation and Raynaud's disease.

Hyperventilation and Raynaud's disease.

A 42 year old woman with long standing Raynaud's disease, unresponsive to medical and surgical treatment, was noted to have a typical history of the hyperventilation syndrome. Rewarming of the hands following cold challenge was markedly prolonged in the presence of hypocapnia. It is suggested that hyperventilation may have an aetiological role in maintaining digital artery spasm in Raynaud's di...

The resting hyperventilation of congenital heart disease.

Existing knowledge of respiratory function in congenital heart disease is limited. Pioneer studies by Campbell et al. (1923) on four polycythaemic patients and one with pulmonary stenosis suggested an increase in resting ventilation, with compensatory decreases in the carbon dioxide fixing power of the blood. More recently, other workers (Bing et al., 1948; Davison et al., 1953; and Holling, 19...

Effects of Hyperventilation Can hyperventilation cause syncope?

Hyperventilation and exhaustion syndrome

Chronic stress is among the most common diagnoses in Sweden, most commonly in the form of exhaustion syndrome (ICD-10 classification - F43.8). The majority of patients with this syndrome also have disturbed breathing (hyperventilation). The aim of this study was to investigate the association between hyperventilation and exhaustion syndrome. Thirty patients with exhaustion syndrome and 14 healt...

Hyperventilation and myocardial infarction.

Chest pain that is associated with hyperventilation is often considered to be benign and noncardiac in nature. While not commonly recognized, hyperventilation can provoke coronary vasospasm. We report a man who presented with hyperventilation and developed myocardial infarction. In the setting of hyperventilation, chest pain and ST segment elevation, coronary vasospasm must be considered.
