Abstract: Abstract: Objective To set up background data reference values of blood pressure and electrocardiogram( ECG) in SHＲ、Wistar rats at different weeks of age． Method The values of body weight、blood pressure and ECG were obtained from 12 SHＲ and 12 Wistar rats since they were at 6 weeks of age to 22 weeks of age． Ｒesult The body weights of SHＲ had been lower than Wistar since 6 weeks of age; heart rate，systolic blood pressure，diastolic blood pressure and mean pressure of SHＲ were all higher than those indexes of Wistar rats，blood pressure became steady since 10 weeks; ECG indexes had been stable with the exception of QT interval and ST interval which were a little lower from 6 to 9 weeks; among these indexes，ＲＲ interval、QT interval、ST interval of SHＲ were higher compared with those of Wistar． Conclusion Background data reference of SHＲ and Wistar from 6 weeks to 22 weeks had been initially established，concluding body weight，blood pressure and ECGs．
