Spectral analysis of the rhythmograms in the cod Gadus morhua callarias, plaice Pleuronectes platessa, herring Clupea harengus membras and trout Salmo gairdneri revealed complex wave structure of their cardiac rhythm. In all the species investigated, slow (0.01-0.06 Hz), intermediate (0.06-0.25 Hz) and fast (0.25-0.5 Hz) waves were recorded. It is suggested that the wave structure of cardiac rhythm reflects rather complicated relationships between functional systems regulating cardiac activity.
对鳕鱼（Gadus morhua callarias）、鲽鱼（Pleuronectes platessa）、鲱鱼（Clupea harengus membras）和鳟鱼（Salmo gairdneri）的心电图进行频谱分析，发现它们的心律具有复杂的波形结构。在所有被研究的物种中，均记录到了慢波（0.01 - 0.06赫兹）、中波（0.06 - 0.25赫兹）和快波（0.25 - 0.5赫兹）。研究表明，心律的波形结构反映了调节心脏活动的功能系统之间相当复杂的关系。
