Ambulatory electrocardiography in car workers.
A previous study in a car assembly plant showed that production-line workers had a lower incidence rate of heart attacks than executive staff. In the present study some major coronary risk factors and 24-hour ambulatory electrocardiograms were investigated in two age-matched samples of 30 middle-aged men drawn from these occupations. Men with a known history of heart disease were excluded. Comp...
متن کاملTwenty-four-hour ambulatory blood pressure in shift workers.
Blood pressure and heart rate of 15 male shift workers were measured every 15 minutes for 24 hours during three work shifts: morning, 4:00 AM to noon; afternoon, noon to 8:00 PM; and night, 8:00 PM to 4:00 AM. For each shift, 24-hour systolic and diastolic blood pressure showed a large "trough" (the low pressure span) and a continuous range of elevated pressure (the high pressure span). Fourier...

Holter monitoring has now come to be synonymous with ambulatory electrocardiography. In hospital practice the term ECG (electrocardiogram) taping is used, often with the prefix 24 hours to indicate the usual duration of the record. A...
متن کاملTwenty-four-hour ambulatory electrocardiography characterization of heart rhythm in Vipera berus-envenomed dogs
BACKGROUND Vipera berus has a worldwide distribution and causes high morbidity in dogs annually. A complication to envenomation may be cardiac arrhythmias. The purpose of this study was to investigate the prevalence, types, and timing of arrhythmias, using 24-h ambulatory electrocardiography (24-AECG), in dogs bitten by V. berus in the first 24-32 h after envenomation. In addition, this study a...
