Abstract
1. 1. Electrocardiograms (ECGs) were recorded from B. bufo and R. pipiens whilst behaviourally aroused and frightened. 2. 2. A tachycardia was exhibited in both states, though in fright it was preceded by a “missed” beat. 3. 3. The difference between these responses and those of other vertebrates was discussed in relation to the amphibious habit. 4. 4. It is suggested that the cardiac responses of diving, fright and arousal may have a common evolutionary origin.
