A. Complete blocking of the neuromuscular junction seen in SfEMG; B. Incomplete blocking: white coloured SfEMG tracings represent the fibres with increased jitter and red coloured fibres present blocking.

Variation of jitter over time in patients who died and those who survived with IMS over time.
(Green represents the range of normal jitter and grey represents jitter >200 μs).
