Electrocardiogram studies in llamas.
Electrocardiograms (ECG) of 3 captive llamas (Lama glama) were recorded by a telemeter at a farm in Japan. The pattern of the ECGs was similar to the ruminant pattern in the AB lead position. QRS and T-waves were discordant in polarity except in one llama, where the polarity of the T wave changed according to the HR. In the quiet state, the HR varied between 60-80/min depending on the nervousness of the llama. After running and after being held, the HR increased to more than 100/min. During the recordings there were some variations of the HR which could be due to respiratory arrhythmia. Second-degree AV block and supraventricular premature complexes were also found in two llamas.
