Abstract
The electrocardiogam of Lipotes "Qi Qi" and "Zhen Zhen" has been recorded since 1980 and compared with those of human and other dolphins. From that, the recording methord and the basic features of the electrocardiogram of Lipotes were described. The normal range of waves, sections and durations of electrocardiogram of Lipotes are very close to those of human, except for the wave T. The direction of wave T in human is in accord with that of the main wave, but the direction of wave T in Lipotes is just opposite to that of the main wave. The duration of P-R is longer than that in human. The results in this study provide an importam basis for the prevention, cure and diagnosis of heart and blood vessel diseases in Lipores.
