Abstract: Abstract：Objective To investigate the electrocardiogram(ECG)features of rhesus monkeys in consciousness． Methods Sixty healthy rhesus monkeys，2—3 years old，2～3．5 kg，and 30 each gender，were selected．ECG changes of the lead I，Ⅱ，11I，aVR，aVL，aVF in resting conscious monkeys were examined，and the average heaM rate，mean electrical axis，P wave，QRS complex，amplitude of T wave，PR interval，QT interval and so on，were calculated．Results and Conclusions Sinus rhythm was found in all the 60 rhesu8 monkeys．In most of the rhesus monkeys，the P wave was upright in H lead，S wave was absent in 1I、Ul、aVF leads，and there was no Q wave in aVR lead．The average voltage of R wave in female rhesus monkeys was significantly higher than that of the males (P<0．005)．In rhesus monkeys，the P wave is sharp，the QRS is diversified，the QT interval K value is 0．298± 0．030，the ST segment locates at the isoelectric line，and the T wave is smooth in six leads and upright in the II lead．In conclusion，we established the basic ECG data of rhesus monkeys．
