Frog Heart

Synopsis

Simulates a number of experiments which can be performed on the heart of a pithed frog to illustrate some important characteristics of heart function. As such it provides a cheap, practical alternative to the use of animals in the physiology laboratory. Produces high-resolution simulations of the frog heartbeat which are displayed on a scrolling screen to simulate a chart recorder. Includes tension and timescales so that measurement of the heart rate and force of contraction can be taken directly from the monitor screen. Traces can be ‘frozen’ to facilitate measurement and hard-copy printouts can be obtained. Experiments included are: effects of adrenaline and acetyl choline, temperature, stannius ligatures, and extra-systole/compensatory pause.
