| Parameter | Prediction threshold |
|---|---|
| nMAPd90 | Reduction by 20% |
| MAPd90–25(ms) | Increase by 20% |
| ΔCL | Increase over 75 ms |
| ΔMAPd90 | Increase over 20 ms |
CL, cycle length; MAPd90, monophasic action potential duration at 90% repolarisation; MAPd90–25, triangularity of monophasic action potential; n, normalised.
