A short questionnaire may be a helpful alternative to routine pre-operative electrocardiography, potentially reducing unnecessary ECGs by 30%.
Electrocardiography is of limited value in pre-operative screening for cardiac disease. A short questionnaire has been shown to be helpful in assessing cardiac status and could permit a 30% reduction in the number of pre-operative ECGs performed.
