What do you do if you receive a shock from your ICD or CRT-D?
If you feel a fast heart beat, be prepared to receive therapy from your ICD within a few seconds.
Stay calm and sit or lie down.
If possible, have someone remain near you throughout the event.
Have a friend or family member call the emergency number if you remain unconscious for more than 1 minute.
If you are conscious but do not feel well after receiving a shock, have someone call your doctor immediately. Follow your doctor's orders, including reporting to the emergency room, if instructed to do so.
If you feel well after the therapy and the symptoms do not recur, you may not need to seek immediate medical attention.
When you do call, your doctor or a nurse may ask you the following questions:
What were you doing immediately before the shock?
How did you feel immediately after the shock?
What symptoms did you notice before the shock?
It is important to prepare your family and friends to contact emergency medical personnel and your doctor. Reserve a space for your local emergency phone numbers and information about your current medications. Keep a copy of this information next to your phone for easy access in case of emergency.
If someone is touching you when the ICD delivers a shock, that person might feel a tingle due to a small, harmless amount of current passing through your skin. They might also feel your muscles twitch or see you "jump" slightly or flail, as if startled.
