If he has no money he has a problem
An ECG alone will cost 3000 or so.
He will see a trainee Dr in his first visit and then he will be referred to a cardiologist a week or two later.
He's looking at several 1000s (Xrays-ECG,EKG etc)
If a CT scan is required, cost will go to the moon...relative to his budget.
Btw.. I'm not in Pattaya but in a big provincial town.
Results may vary ,as they say..
