Effect of apamin on the percentage of APD prolongation in normal and HF ventricles. A, APD80 before (blue line) and after (red line) apamin infusion, and the percentage of APD80 prolongation at PCL 350, 300, 200, 180, and 160 ms in a normal and a HF ventricle. B, PCL and the percentage of APD80 prolongation by apamin in all normal and HF ventricles. Note that the differences between HF and normal ventricles were significant only at very long (350 ms- 300 ms) and short (170 ms- 160 ms) PCLs (see asterisks), but not with intermediate (280 ms- 180 ms) PCLs.
