Abstract：Objective To study the clinical value of dynamic dectrocardiogram in detecting silent myocardial ischemia（SMI）for patients with coronary heart disease. Methods One hundred and thirty eight patients with coronary heart disease were detected by 12 lead dynamic electrocardiogram for 24 hours. Results There were 439 SMI episodes（85.08%） in total 516 episodes ST segment depression with myocardial ischemia. Conclusion The incidence for SMI in coronary heart disease patients was very high. And the dynamic dectrocardiogram in detecting SMI has many advantages，such as high sensitivity and high accuracy.So it is significant for the prevention of SMI.
