Abstract：Objective Analyzing the changes of QT dispersal degree (QTd) of cardiogram of unstable anginal patients and healthy adults and exploring the effect on QTd of unstable anginal patients by using β1 retarder-metoprolol.Method Measuring QTd of 86 unstable anginal patients by using body surface synchronical 12 leads cardiogram and comparing the results with that of 86 healthy adults.The 86 unstable anginal patients are randomly divided into metoprolol group of 40 people and blank check group of 46 people.After 6 weeks’observation,measure QTd of the two groups using body surface synchronical 12 leads cardiogram and compare and analyze results of the two groups.Result The QTd difference between the group of unstable anginal patients and group of healthy adults is remarkable(47.24±21.14 ms vs 33.46±7.14 ms,P＜0.01),and QTd difference between the group of metoprolol and blank check group is remarkable (34.26±6.83 vs 46.18±18.04,P＜0.01).Conclusion The QTd of unstable anginal patients is increased remarkably and metoprolol can reduce QTd of unstable anginal patients.
