Also, I am going to see Dr. KUSUMOTO at Mayo Jax to review my a fib treatment to date. I want a second opinion on my meds and his advice on how to proceed in the future.
Find a electro cardiologist you trust.

Hi -- A few hours ago I asked on this board the question of why metoprolol is not a favored medicine. And many of you people are weaning off of it (with guidance by your doctors). I just started reading (listening) to a book "Bottle of Lies" which educated me on how generics are produced in China or India and other countries and are then sold to the USA. And generally it happens that generics can be contaminated or not effective etc. The FDA does inspect these foreign drug factories - but generally the FDA inspectors do not have access to the parts of the huge buildings where the generics are made. Plus generally the FDA inspectors don't even KNOW that there are facilities in the huge campuses where the testing goes on. This book tells it ALL (at least where the inpectors know to look). Otherwise the inspectors are given a VIP welcome and taken on a tour of the drug company which only shows the labs and offices that the Chinese Drug Companies want outsiders to see. (i'm generalizing I know -- there must be a Honest Drug maker in china.) if you want to have your eyelids opened then read this book. I got the audiobook from audible.com. The author states that one of the "biggies" is metoprolol ethyl succinate. Plus in the USA the FDA inspectors can and do "drop in" unannounced. However in China the FDA inspectors have to notify the drug makes FAR in advance - which you all know give them time to rush around crazily and clean up every corner, polish and clean every surface, dress themselves in dazzling whites. Which we would certainly do if we happened by circumstances to be born as a Chinese, and have been fortunate to get a good education in the sciences including pharmacology.
