Representative experimental recordings. Sample left ventricular pressure recordings illustrate responses during baseline (BL), cardioplegic perfusion (CP), ischemia, and reperfusion (RP). The baseline section showed normal cardiac function during initial perfusion of the heart. When the heart was perfused with hypothermic STH2 cardioplegia, all the contractile activity ceased and a rapid cooling contracture was seen. During ischemia, the heart relaxed. Contractile activity recovered to varying extent in reperfusion. a Young male. b Old male. c Young female. d Old female
