흉통의 진단에 다단계 답차 운동부하 검사의 의의

Abstract

From 1985 to 1987, we performed the treadmill exercise test on 206 patients who had been suffering from anterior chest pain, suspected angina pectoris. Among the subjects, male to female ratio was 1.8:1, the mean age was 50 years old, and the most prevalent age group was 6th decade (36%). 89 cases revealed positive results(depression of ST segment > 1mm, shape of ST segment depression, or could not finish stage 2 of Bruce protocol, which represent multiple-vessel disease. Depressed ST-segment showed any site of 12leads, but the most common lead group was V5-6 (89%), and the next one was II, III, AVF (71%), and the least one was I, AVL (4%). The relationship between the degree of ST segment depression and the number of changed leads, showed positive correlation (p>0.01). During the test, serious complication occured. In conclusion, we consider that the treadmill exercise test is a very useful, noninvasive and objective method to assess the ischemic heart disease.
