A new look at the comparative physiology of insect and human hearts

Popis výsledku v původním jazyce

Recent electrocardiographic (ECG) studies of insect hearts revealed the presence of human-like, involuntary and purely myogenic hearts. Certain insects, like a small light-weight species of hoverfly (Episyrphus balteatus), have evolved a very efficient cardiac system comprised of a compact heart ventricle and a narrow tube of aorta, which evolved as an adaptation to sustained hovering flights. Application of thermo-cardiographic and optocardiographic ECG methods revealed that adult flies of this speciesuse the compact muscular heart chamber (heart ventricle) for intensive pumping of insect "blood" (haemolymph) into the head and thorax which is ringed all over with indirect flight musculature. The recordings of these hearts revealed extremely high, record rates of forward-directed, anterograde heartbeat (up to 10 Hz), associated with extremely enhanced synchronic (not peristaltic) propagation of systolic myocardial contractions (32.2 mm/s at room temperature). The relatively slow, back
