She had to do a tilt table test today because she has been passing out. While she was there they decided to implant a loop recorder to be able to tell what her heart is doing as she goes about her day. They wanted to put a monitor on her for a month to six weeks but she has a reaction to the adhesive that is used with that so this was what they decided to do.
She is back in the room and feeling fine. Unless she has a problem she should be leaving in about another hour.
