Abstract
The patient was a 24 year-old female having hyperventilative attacks which were accompanied by arrhythmia. She was diagnosed as hyperventilation syndrome with premature beats which were precipitated by an emotional stress caused by the death of her lover.Her premature beats as well as hyperventilative attacks, were recorded under a stress interview.These results indicate that such an emotional stress could play an important role in the development to hyperventilative attacks with arrhythmia.
