Effect Of Chronic Heavy Alcohol Intake On The Heart Investigation By Electrocardiography Mainly

Abstract

Fourty three male subjects without any cardiac symptoms or signs, who had been drinking for a mean of 12.5 years range (5-25 years), their ages ranged from 20-55 years. These subjects, and thirty seven non drinking controls from the same environment, and matched for age; had their cardiac functions studied using electrocardiography, some very few subjects were also studied by echocardiography and chest x-rays. There were no abnormalities found either on electrocardiography or on the few echocardiographs and chest x-rays. The negative results in this study may mean that subjects had marked alcohol tolerance, possibly due to their general physical fitness, or the myocardial abnormalities could not be picked up by the methods used, or a possible sampling bias.
