【 摘 要 】

Knowledge of cardiac parameters in experimental animal models is essential for comparative medical research. Our study aimed to establish electrocardiographic parameters and reference values for marmosets (Callithrix penicillata). Nineteen healthy adult marmosets were used. A combination of tiletamine and zolazepam was used for chemical restrained before performing electrocardiography (ECG). A computerized ECG machine was used. Values of the ECG parameters were a mean heart rate of 264±74 beats/min, a variation MCA between 60° and -90°, a mean P wave duration of 34±6ms and amplitude of 0.132±0.051mV, a mean PR interval duration of 56±11ms, a mean QRS complex duration of 35±7ms and amplitude of 0.273±0.269mV, a mean QT interval duration 130±26ms, ST segment was isoelectric (13 animals) and with elevation (six animals) and a mean T wave amplitude of 0.19±0.083mV and positive. There was no significant difference between males and females. Thus, the electrocardiographic parameters obtained in our study in marmosets can be used as a reference values to in other future researches, providing researchers electrocardiographic parameters that contribute with the literature.
