The electrocardiogram of the cheetah (Acinonyx jubatus).
Electrocardiograms were recorded on 19 cheetahs immobilized with the steroidal anaesthetic-hypnotic agent Saffan comprising 0,9% m/v alphaxalone and 0,3% alphadolone. Sinus rhythm was recorded in all animals and heart rate was rapid averaging 173 +/- SD 18 beats per minute. The average of mean electrical axes in the frontal plane was + 76 degrees +/- SD 13 degrees. Mean +/- SD durations in milliseconds on lead II were: P 47 +/- 6,5; PR 93 +/- 11,5; QRS 53 +/- 7,5; QT 193 +/- 19,7. The amplitude of limb lead electrocardiographic complexes were low, resembling those of the domestic cat more closely than those of the dog.
