question: My husband went into Vfib or Vtac 12 to miss in 2 hours. They got him stable after 6 hours, the paddles twice and lydocaine and amiodorone injections. They placed a stint in his LAD which was 98% blocked and that seems to have fixed the problem. He has been wearing a vest for the last 3 months with a built in defibrillator and has had no incidents. He is off the amiodorone now and just on the blood thinner. Yesterday they did an echo on him. They are concerned about damage that may have occurred during the crazy 6 Hour episode last Nov. what should be most concerned about going forward?
