OBJECTIVE: To characterize the electrocardiogram (ECG) of anesthetized adult emus (Dromaius novaehollandiae). ANIMALS: Ten clinically healthy adult emus anesthetised for routine physical examination and an electrocardiogram, for both monitoring and investigation into any evidence of cardiac disease. METHODS: The ECGs for each emu were obtained in right lateral recumbency, using a modified electrode placement that replicated the standard bipolar leads used in small mammals. Lead II was used for waveform analysis. RESULTS: Median P wave amplitude was 0.55 mV (range: 0.2-0.92 mV) and P wave duration was 0.06 s (0.04-0.09 s). S wave amplitude measured 1.42 mV (0.92-2.12 mV), T wave amplitude 0.67 mV (0.16-0.83 mV) and QRS duration was 0.07 s (0.07-0.12 s). Ninety percent of the QRS complexes were of rS type. CONCLUSION: Our study provides electrocardiographic baseline data for anesthetized adult emus.
