摘　　要：目的探讨经食管心脏调搏S1-R段的下移改变对冠心病的诊断价值。方法对86例非心脏病患者、59例冠心病患者和38例其他心脏病患者，先描记常规12导联心电图，继而采用心脏程控刺激仪用比受检者自身快20次／min的心率起搏心脏，连续刺激30s，并用Ⅱ导联记录最后8s的心电图供分析。结果心脏病患者S1-R段下移率明显高于非心脏病患者，冠心病患者S1-R段下移率显著高于其他心脏病患者。结论经食管心脏调搏S1-R段自身对照下移≥0．2mV时，可做为诊断冠心病的重要指标。Objective To explore the diagnosis value of S1-R segment depression caused by transesophageal atrial pacing for coronary heart disease. Method Used 12-lead ECG to measure 86 cases with non-cardiac disease, 59 cases with coronary heart disease, and 38 cases with other heart diseases. Then cardiac stimulator was used to pace the heart with the HR of 20 beats/min higher than themselves; the time of continuous stimulation was 30 seconds; the Ⅱ -lead ECG of last 8 seconds was recorded and analyzed. Results The rate of S1-R segment depression in heart diseases was higher than non-cardiac disease; which was positively correlated with coronary heart disease. Conclusion The SI-R segment depression was 0.2 mV more than themselves. That can be used as an important diagnostic index for coronary heart disease.
