本文报道了小型鱼类深虎鱼(Bathygobius fuscus)的心电图。采用双电极接近围心腔的方法导出,向口内灌流水模拟鱼的呼吸运动。实验表明心脏搏动电位与灌流强度成正比关系;心搏率几乎与灌流强度无关,主要受水温的影响,随着水温的升高,心搏率明显增加。本种鱼与陆上一般动物不同,其心搏率几乎与运动强度无关。 This article reports the electrocardiogram of the small fish, Bathygobius fuscus. Using two electrodes approach the pericardial cavity approach, the mouth of the water flow to simulate fish breathing exercise. Experiments show that the heart beat potential and perfusion intensity is proportional to; heart rate almost independent of perfusion intensity, mainly affected by water temperature, with the increase of water temperature, heart rate increased significantly. This kind of fish is different from the general land animals, and its heart rate is almost independent of exercise intensity.
