Table 2 Comparison of the inverse ratios of the relative edge areas of the various-sized cardiac models with the ratio of the transverse propagation velocities (θtr)

From: Boundary effects influence velocity of transverse propagation of simulated cardiac action potentials

  Model Size Ratio of relative edge area to interior area θtr cm/sec Velocity A/Y Area Y/A
A 7 × 7 28/49 = 0.57 4.7 -- --
B 5 × 5 20/25 = 0.80 3.4 1.38 1.40
C 3 × 4 14/12 = 1.17 2.5 1.88 2.05
D 2 × 3 10/6 = 1.67 1.9 2.47 2.93
  1. Orthodromic direction; stim of entire A-chain; values for Rol2 of 200 KΩ.
  2. Y equals value of B, C, or D.
  3. The equation relating these parameters is:
  4. Where a single asterisk superscript (*) denotes the values for the smaller model compared to the referral 7 × 7 model (denoted by double asterisk**).
