Frog Heart

a computer simulation of experiments which may be performed on frog heart

By: David Dewhurst and Malachy Doherty

An interactive, menu-driven and easy to use program which simulates a number of experiments which can be performed on the 'in situ' heart of a pithed frog. High-resolution simulations of contractions of the frog heart, derived from real data, are presented on a scrolling display to simulate a chart recorder. The trace may be paused to facilitate measurement of heart rate or to assess changes in the amplitude of atrial or ventricular contraction. Experiments include:

Interpretation of a typical trace;
the effects of adrenaline;
the effects of acetylcholine (with physostigmine or atropine);
the effects of temperature;
refractory period;
electrical conduction through the heart (Stannius ligatures).

Each experiment is prefaced by introductory text and includes an experiment guide and assignments.
