Aim:
To introduce the manufacture and use of a simple, new type of drop recorder of frog heart.
Methods:
To improve the perfusion device of (see text for symbol) and Straub method. Two electrodes of drop recorder were fixed in an injector of 20 ml. The input tube, output tube and resistance tube were all made of plastic material.
Results:
This device could be used to observe effects of preload, after-load, hormone and electrolyte on the cardiac output in isolated frog heart.
Conclusion:
The new type of drop recorder was economical and could be easily operated, it could be also connected to computer. Using the new type of drop recorder, effects of various physical and chemical factors on cardiac function could be observed directly, accurately.
