Most modern ECT devices deliver a brief-pulse current, which is thought to cause fewer cognitive effects than the sine-wave currents which were originally used in ECT. A small minority of psychiatrists in the US still use sine-wave stimuli. Sine-wave is no longer used in the UK or Ireland. Typically, the electrical stimulus used in ECT is about 800 milliamps and has up to several hundred watts, and the current flows for between one and six seconds.Lock, T (1995). "Stimulus dosing".
