title: Hyperventilation: An important cause of pseudoangina.
abstract: 50 patients initially referred to a cardiac clinic for confirmation or exclusion of angina were found to be habitual hyperventilators. 13 of them also had some organic heart disease. Simple physiotherapy aimed at restoring a normal breathing pattern proved an effective treatment, 76% of those followed for 11-68 months being symptom-free.
