[The technical requirements of simulating cardioplegia and perfusion of an isolated heart].

A testing unit for simulating cardioplegia and restorative perfusion of an isolated heart is described. The testing unit is fitted out with a chamber for an isolated heart, an oxygenator, a heat exchanger, the perfusion system and organs controlling heart work under different conditions of perfusion and cardioplegia. The system approximates the physiological condition of the experiment and allows changing and controlling them on a broad enough scale.
