Changes in paramagnetic centres (PC) concentration in rabbit’s myocardial muscle were studied under experimental myocardial infarction during 168 hours by means of ESR-spectroscopy. PC characterized by ESR signal with g = 3.0 was found. It was shown that hyperbaric oxygenation did not affect PC content in the infarction zone, and resulted in an increase of PC concentration with g = 1.94 and g = 2.0 in the intact myocardial zone.
