Electrocardiographic parameters and heart rate variability in free-ranging Jaguars (Panthera onca) immobilized with tiletamine-zolazepam-dexmedetomidine.

ABSTRACT: Understanding the physiology and particularities of wild felids is important for improving the ability of veterinary medicine to contribute to the preservation of these species. Thus, the objective of this study was to describe the electrocardiographic parameters and heart rate variability (HRV) of wild jaguars (Panthera onca) captured in Brazil. The anaesthetic protocol used for chemical restraint of the animals involved the drug combination of tiletamine and zolazepam (7 mg/Kg) along with the α2 adrenergic (receptor) agonist dexmedetomidine (10 µg/Kg). The 42 electrocardiographic reports from 39 animals were categorized (sex, estimated age, and body weight) and statistically analysed; 25 females and 14 males between two and 21 years old with a mean weight of 80.96 ± 23 kg were analysed.
