Comparison of mean durations of seizure phases (in seconds), post-ictal generalized EEG suppression and recovery phases in the primary GTCS of genetic generalized epilepsies and secondary GTCS of focal epilepsies.
| PHASE (in seconds) | PRIMARY GTCS (N=19) | SECONDARY GTCS (N=86) | SIGNIFICANCE |
|---|---|---|---|
| Total seizure duration | 76.2 ±37.94 | 111.62±54.2 | 0.008* |
| Tonic | 7.42±2.73 | 10.08±3.78 | 0.005* |
| Clonic | 53.16±37.56 | 49.48±26.02 | 0.611 |
| PGES | 16.26±21.72 | 36.51±24.55 | 0.001* |
| Recovery | 19.63±58.01 | 32.29±43.48 | 0.028* |
