FIELD: medicine.
SUBSTANCE: invention refers to medicine and namely to experimental cardiology. During the experiment there made is the measurement of heart swelling in calcium-free medium. At that, myocardium diastolic pressure is measured continuously and swelling is calculated by the following formula: where: W - water content in myocardium, ml/g, dry basis, mwot - wet tissue mass after calcium-free perfusion is completed, gram, mdry - dry tissue mass, gram, Pdiastolic - gastric pressure of the stopped heart, mm Hg. Po - initial diastolic pressure created artificially with the investigator and usually equaling to 20 mm Hg.
EFFECT: reducing labour input when measuring water content in myocardium.
