Holter for Lolo

Mom and dad will be accompanying lolo (grandfather) to the hospital on Monday.  The doctor will be putting patches on his chest.  He wants to monitor lolo's heart's electrical activity. While the holter monitor is with him, my mom will keep a diary of what he does while wearing it.  Then they'll  return it after 48 hours. His doctor will look at the records and see if there have been irregularities in his heart rhythms.  Lolo has been complaining of shortness of breath and mom got worried so they're off to see his doc on Monday.
