As you saw with the TOF, the response-pattern to a tetanic stimulus also varies between depolarizing and non-depolarizing NMB.

1. Prior to neuromuscular blockade
2. During partial neuromuscular blockade by succinylcholine
3. During partial neuromuscular blockade by a non-depolarizing muscle relaxant
4. Post-tetanic facilitation in the presence of deep block by a non-depolarizing muscle relaxant
