Thanks profdant: I wouldn't let my condition change any plans we have for Mexico but it certainly has caused me think about emergencies in a new light. I have been ill in Mexico many times but never anything serious. I can think of many places we have visited with 3rd world facilities and in some cases these facilities are not close by. There are lots of horror stories of tourists in Mexico who have encountered expensive hospitals that are almost "fake". Mazatlan is famous for these quack clinics. It's one thing to have some facility set your broken leg and it is not done right. Playing with my heart is just a little more serious. I never intended to scare anyone . I was just bringing to light that travelers should consider the availability of medical care.
