摘要

運動心電圖是針對臨床上懷疑有缺血性心臟病的族群所進行的檢查，雖然靈敏度與特異性比不上鉈－201心肌灌注檢查或心導管檢查，卻能作為非侵入性且方便的篩選工具。然而，運動心電圖在軍方飛行員這個健康的族群中卻會大幅增加偽陽性之可能性。本文主要探討如何提高運動心電圖及其他相關檢驗，增加運動心電圖對於無症狀之空勤人員的篩選能力，以促進飛行員之健康。

Although the sensitivity and specificity of exercise electrocardiogram is not comparable to Tl-201 myocardial perfusion scan or cardiac catheterization, it is used broadly to evaluate the risk of coronary artery disease because of its low cost and non-invasiveness. However, the false-positive rate of exercise electrocardiogram could be high when used in a relatively healthy population such as military aviators. This article discusses the potential pitfalls of using exercise electrocardiogram and reviewed some other diagnostic tools that may increase the sensitivity of this test.
