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 |
- Orthodromic direction; stim of entire A-chain; values for Rol2 of 200 KΩ.
- Y equals value of B, C, or D.
- The equation relating these parameters is:
