Figure 1.

Figure 1

PCL and the effects of apamin on APD prolongation. A and B show HF and normal ventricles, respectively. Note that HF ventricles have longer baseline APD than normal ventricles. Apamin prolonged APD in HF but not in normal ventricles. C and D, APD associated with different PCLs at baseline and after apamin infusion in HF and normal ventricles, respectively. Error bars represent standard deviation. The HF ventricles but not normal ventricles showed significant APD prolongation at long and short PCLs. The p-values in Figure 1C are corrected by Bonferroni method for multiple comparisons. Asterisks indicate corrected p<0.05. LAD, left anterior descending coronary artery; RV, right ventricle; LV, left ventricle.
