This depressant effect is enhanced by increasing blood levels 75 milligrams/100 milliliters, but remains for only a few hours after ingestion ceases. However, the amount of blood the heart can pump per minute may actually increase in normal subjects acutely exposed to alcohol, because of an acceleration of the heart rate (increase of contractions per minute).

During the late-intoxication/early-withdrawal stage of acute alcohol consumption, blood pressure may be affected in the noncardiac alcoholic. Blood-pressure...
