短暂刺激疗法（BST）是作为经典电击的替代技术而开发的，它被认为使用了不必要的大amt。的电能。在经典技术中，采用60个周期的普通市电电流，每个脉冲由2个半波组成，每个半周期持续8毫秒。因为已经表明，超过2毫秒的脉冲持续时间不会对惊厥效应产生额外的能量，所以在该替代技术中使用较短的脉冲持续时间，范围为0.5至0.7毫秒。在经典的电击中，刺激的总持续时间约为0.4秒。在BST 1到1.3秒内。是最佳的。BST中的刺激频率是每秒120次而不是60次刺激。传统技术中的电极位置是双颞的;在BST中，通常使用左或右的顶颞位置。传统电击的电流幅度约为800毫安;在BST中使用的电流要低得多，为14至40毫安。BST中的延迟时间通常小于1秒，很少超过2秒，与长达50秒的反应时间相比，在传统技术中。两种治疗的惊厥模式基本相同，尽管BST的初始哭声较少，惊厥时间稍长但不太严重。有些癫痫发作是非常轻微的，在这些患者可能是清醒的，甚至声称感知到有节奏的运动。在惊厥后阶段，BST产生较少的混乱，一些患者显示出完美的接触，同时仍然呼吸困难。BST患者对治疗有更强烈的反感，但几乎没有记忆丧失，脑电图变化较轻，35%的患者在10次惊厥后没有变化，只有10%的患者显示波慢于每秒5次。治疗结果似乎等同于电击，BST结果是从一系列46例患者中估计的。
Brief Stimulus Therapy (BST) was developed as an alternative technique to classical electroshock, which it was felt uses an unnecessarily large amt. of electrical energy. In the classical technique, ordinary city current at 60 cycles is employed, each pulse made up of 2 half-waves, and each half cycle lasting 8 milliseconds. Because it has been shown that pulse durations over 2 milliseconds do not contribute additional energy to the convulsive effect, briefer pulse durations are used in this alternative technique, ranging from 0.5 to 0.7 milliseconds. In classical electroshock the total duration of stimulation is about 0.4 sec. in BST 1 to 1.3 sec. are optimum. The frequency of stimulation in BST is 120 rather than 60 stimuli per sec. Location of the electrodes in the conventional technique is bitemporal; in BST the vertex-temporal position, left or right, is usually used. The current amplitude in orthodox electroshock is about 800 milliamperes; in BST the current used is much lower, 14 to 40 milliamperes. The latency time in BST is usually less than 1 sec., and rarely over 2 sec., compared with reaction times as long as 50 sec. in the conventional technique. The convulsive pattern is essentially the same in both types of therapy, although in BST there are fewer initial cries, and a slightly longer but less severe convulsion. Some of the seizures are very mild, and during these the patient may be awake, and even claim perceiving the rhythmic movements. In the post-convulsive period, BST produces less confusion, some patients showing perfect contact while still dyspnoeic. There is more vivid antipathy to therapy in BST, but practically no memory loss, EEG changes are milder, 35% showing no changes after 10 convulsions, and only 10% showing waves slower than 5 per sec. The therapeutic results seemed equal to electroshock, the BST results being estimated from a series of 46 patients.
