Electroconvulsive Therapy

(Therapy, Electroconvulsive; ECT)



Electroconvulsive therapy (ECT) sends an electronic current through the brain. This current causes brief seizure activity. This causes changes in brain chemistry.

  • Short-term changes in your heartbeat
  • Headache
  • Nausea
  • Muscle aches or soreness

  • A history of heart problems, stroke, or high blood pressure
  • Pregnancy—may increase the risk of problems for the baby

What to Expect    TOP

Prior to Procedure

You may have:

  • A physical exam
  • To talk about all the medicines you're taking
  • Some tests such as an ECG to test your heart or brain scans
  • Instructions on food or drink limits before the procedure

You may feel confused after ECT. Arrange for a ride and for help at home.


General anesthesia will be used. You will be asleep.

Description of Procedure    TOP

Oxygen is given through a mask. A mouth guard may also be placed in the mouth. This will protect the tongue and teeth from getting hurt. Next, electrodes will be placed on the head. They will be hooked up to a machine. It will send an electric current to the brain. This will cause a seizure. After the shock is given, some muscles will contract for a few seconds. Next, the body will twitch, which can last up to a minute.

Immediately After Procedure    TOP

You will be taken to a recovery room where your vital signs will be watched. You will wake up in 10-15 minutes. You may feel confused. This confusion can last minutes, hours, or sometimes longer.

How Long Will It Take?    TOP

About 30 minutes, including time to recover after the procedure

How Much Will It Hurt?    TOP

You will not feel any pain during the procedure. After ECT, you may have a headache, and muscle aches or soreness.

Post-procedure Care    TOP

At the Care Center

When you are fully awake, you will be given something to eat and drink. In most cases, you will be able to go home the day of the procedure.

At Home

You will need to schedule an appointment for another ECT treatment. In most cases, you will need to have 2-3 treatments per week, for many weeks. You will need to take medication, such as antidepressants, and continue with therapy to prevent a relapse.

You may also need maintenance ECT to further prevent a relapse. Your doctor will help determine the right plan for you. This will depend on how you are progressing.


Call Your Doctor    TOP

Call your doctor if you have any of these:

  • Worsening of symptoms, including feelings of hopelessness or helplessness and thoughts of suicide—If you have thoughts of suicide, call your doctor or therapist right away.
  • Confusion and memory loss that lasts longer than expected.
  • Headache, muscle aches, or soreness that lasts longer than expected.

If you think you have an emergency, call for emergency medical services right away.
