Just anecdotal, but I visited Shanghai this summer and toured a top clinic - from my perspective, their standard of care is on par with, if not better, than many large (and quite good) groups like Sutter Health or Straub. The doctors there were educated in the U.S. and Germany (Massachusetts and Munich if memory serves).

Plus, if you can wait, treatment is nearly free, but you can get same day service for many procedures, like overnight ecg, for say $100 -$200.
