Effects of morphine on the incidence of conduction block and arrhythmia during simulated ischaemia (left panels) and reperfusion (right panels). Every 2 min during the ischaemic period (30 min) and the reperfusion period (30 min), values are expressed as percentages of preparations presenting conduction blocks between the two myocardial regions and spontaneous arrhythmias, defined as disturbances. Results are reported in the absence of drug (top panels) and in the presence of 0.01 μM (middle panels) and 0.1 μM morphine (bottom panels).

Effects of morphine on the incidence of loss of responsiveness to constant stimulation intensity, arrhythmias and conduction blocks during simulated ischaemia and reperfusion periods. Data are expressed as percentage of preparations with disturbances during the experiments.
