at Children's Hospital Boston answered the following questions:
Some people's heart can go much too fast. This
can make them can feel bad and even pass out. A defibrillator can
prevent this from happening.
A defibrillator is a small device that counts
every heartbeat. If the heart is beating too fast, then the defibrillator
sends a burst of energy to the heart, which sends the heart back
into its normal rate.
I am not sure exactly what this feels
like, but other kids have said it is like "having something thrown
at my back" and "being punched in the chest." To be honest, I know
it does hurt however it seems to only do so for a few seconds and
then the pain is gone.
