Background: Ultrasound cardiogram plays an important role in evaluating cardiac function of patients with coronary heart disease before and after rehabilitation.Wall motion,function of contraction,and cardiac function could be evaluated using ultrasound cardiogram.Sensitivity of visual method in evaluating wall motion is not high.Color kinesis(CK) is a kind of new technology.rnObjective: To study sensitivity and accuracy of CK and visual method in evaluating wall motion.rnDesign: In order to test sensitivity of CK,we compared CK and visual method.rnUnit: General Hospital of Shenyang Military Region rnSubjects:120 patients suffered from coronary heart disease during 1998～ 2000,78 male,42 female,aged from 36～ 72 years(mean:54 years).All patients had history of precardial pain,and ST-T changes were found in ECGs.rnIntervention: Coronary arteriography was done on all patients.To observe wall motion using visual method and CK.Color Doppler inspector HP2500 with a probe(2.5MHz/2.0MHz).Patients lied in horizional position.Then CK examination was done after defining endocardium.Simularly,electrographic signals were recorded.Endocardial motion were numbered colorfully.
