"my husbands treatment"

my husband came to hosp in May as emergency as his oxygen stasts were low. He was given nabuliser and had chest xray done. Later a A&E doctor on duty said that he will have to stay in for few days as they need to investigate his respiratory problem. I left my husband in hospital on thusday and returned on friday only to be told that he was being released as his oxygen levels were fine.And on Saturdaynight/Sunday morning he suffered a massive heart attack and he had lungs complications. He was to taken to Royal Free Hosp, where he received excellent treatment and my husband regained consicousness after three weeks in ICU.Northwick park needs to learn patient care. Very poor standards.
