The experimental data recorded from two guinea pig ventricles using a dual-electrode catheter. (A) Recorded signals from the tip electrode with the ring off (blue) and on (orange) are given. The horizontal bar represents 100 ms, and the vertical bar is 10 mV. Each recording was 20 s long. (B) The power spectra of the signals shown in (A) are given. (C and D) The experimental (open circles) and analytic (black line, calculated using Eq. 15) ratios of the transfer functions (the ring on/ring off ratio) for the two ventricles are shown.
