Electroconvulsive therapy, also known as ECT or electroshock therapy, is a Tau'ri psychiatric treatment in which seizures are electrically induced in patients. One application to the treatment is to deprogram people who were brainwashed. Though initially viewed as barbaric, in 1998 Janet Fraiser noted that recently all trials were more controlled as the patients were put under anesthesia as the therapy took place. Being shot once with a Zat'nik'tel apparently has the same effect. (SG1: "Family")
When Rya'c was brainwashed by Apophis in 1998, Frasier considered ECT to deprogram him. However, Teal'c suggested using a Zat'nik'tel instead, which he believed carried the same effect; the method proved successful and Apophis's control over Rya'c ceased. (SG1: "Family")
