Does 0.5 ms pulse width ECT reduce clinical response compared to 1.0 ms pulse width ECT?
1.0 ms pulse width ECT should be used as standard over 0.5 ms pulse width to maximize clinical response, unless cognitive sparing is paramount.
This study demonstrated a previously unreported association between 0.5 ms pulse width and reduced ECT response. Unless cognitive sparing is paramount in an individual case, 1.0 ms ECT should be used as standard.
Braithwaite et al. (Thu,) studied this question.
