| Abstract: | Leads I, aVF, V3, and V10 ECG were obtained from 12 healthy raccoons anesthetized with xylazine and ketamine. Intervals and amplitudes of component deflections were remarkably uniform among the individuals. Vector orientation of QRS mimicked that for the dog; but the relatively low voltages to QRS mimicked those of cats. The QT interval varied inversely with heart rate, whereas the PQ interval varied directly with body weight. Relationship between heart rate and body weight was not significant (P greater than 0.05). |
