My Husband Had A Pacemaker Put In 4 Weeks Ago.

my husband had a pacemaker put in 4 weeks ago. it was a total heart blockage. He was given compression in ER 4 times before the temporary pacemaker was put in. Lucky to be here. He still doesn't feel well and has has gotten dizzy and nausea since.Is this normal. Also he has a enlarged arety Kawasaki Disease is what we were told it was. This was ten years ago when it was last checked. Shouldn't this be checked again?
