Bioelectric impedancemetry of the myocardium during cardiac surgery with artificial circulation.

We analyzed changes in bioelectric impedance of the myocardium during cardiac surgery under conditions of cardioplegy. The results suggest the possibility of using bioelectric impedancemetry for evaluation of the state of the myocardium during surgery. Bioelectric impedancemetry allows evaluation of interstitium filling during infusion of the cardioplegic solution and reperfusion damage to cardiomyocytes.
