The aim of this study is to evaluate the reference value for electrocardiogram in healthy captive raccoon dogs. Forty-one free-ranging adult raccoon dogs rescued from Wildlife rescue centre, Kangwon National University were enrolled in this study. The 6-lead electrocardiogram was obtained in all raccoon dogs without any chemical restraints. The mean heart rate was 146.10 ¡¾ 43.31 beats/min (95% confidence interval 132.84~159.36 beats/min). The mean respiration rate was 35.73 ¡¾ 11.56 breaths/min (95% confidence interval 32.19~39.27 breaths/min). The mean systolic blood pressure was 136 ¡¾ 29.26 mmHg (95% confidence interval 127.99~145.91 mmHg). Electrocardiographical features were also evaluated in all raccoon dogs. The mean duration and amplitude of P-wave were 38.2 ¡¾ 4.0 ms(range 28-40 ms) and 0.128 ¡¾ 0.039 mV (range 0.09~0.20). The mean duration and amplitude of QRS complexes were 48.5 ¡¾ 7.2 ms (range 36-60 ms) and 1.330 ¡¾ 0.650 mV (range 0.15~2.30). The range of the mean electrical (QRS) axis was ?91o~ +96o (10o~60o; 95% of confidence interval). The mean corrected QT (QTc) interval was 273.7 ¡¾ 32.7 ms (range 212-333 ms), while the mean PR interval was 76.1 ¡¾ 10.0 ms (range 50-82 ms). To the authors' knowledge, this is the first study to provide references in electrocardiogram (ECG) in healthy captive raccoon dogs. ÁÙÀ̱â
