Effects of hypoxia and reperfusion on the contractile function of cardiomyocytes. An example of the recording obtained during the experiment. The trabeculae's contraction amplitudes are shown for remifentanil (above) and the control (below). A profound decrease in trabeculae contraction results from ischemia. At the end of 60 min of ischemia, oxygen is again applied (reperfusion), and opioid is added to the study probe. Higher contraction amplitudes are noted for the remifentanil probe
