Physiological and clinical researches on aquatic mammals have not been much conducted in most fields. Especially, the cardiovascular physiological studies including heart were hardly carried out. In small cetaceans, however, several areas of this research field, such as normal ECG waveform and histology of cardiac conduction system, have been studied by our laboratory. There are many aquariums in Japan now. It is expected that aquariums and educational and research institutions such as veterinary school establish the collaborations for investigations each other.
