Neurocirculatory Asthenia

Da Costa's syndrome or neurocirculatory asthenia.

The syndrome variously called Da Costa's syndrome, effort syndrome, neurocirculatory asthenia, etc has been studied for more than 100 years by many distinguished physicians. Originally identified in men in wartime, it has been widely recognised as a common chronic condition in both sexes in civilian life. Although the symptoms may seem to appear after infections and various physical and psychol...

Electrocardiographic characteristics of neurocirculatory asthenia during everyday activities.

We describe the electrocardiographic changes during everyday activities recorded by ambulatory electrocardiographic monitoring in 67 patients with neurocirculatory asthenia. The findings were compared with the results of ambulatory monitoring in 33 healthy controls. We observed episodes of sinus tachycardia > 120/min unrelated to effort in 60 of the patients, 35 had frequent episodes of pronoun...

Life situations, emotions and neurocirculatory asthenia (anxiety neurosis, neurasthenia, effort syndrome).

Effects of beta-receptor blocking agents propranolol and practolol on ST-T changes in neurocirculatory asthenia.

In Io patients with neurocirculatory asthenia the effect of two adrenergic beta-blocking drugs, propranolol and practolol, were studied on the ST-T changes observed in the resting electrocardiogram and on those occurring under orthostatic conditions. The drugs were administered intravenously on different occasions. Propranolol improved the ST-T abnormalities in the resting electrocardiogram in ...
