question: My aunt just had a heart valve replacement and was released from the hospital about 2-3 days ago. I found out this evening that she is back in ICU. It s my understanding that her heartbeats that should be @ 100 drops to 50 and that they plan to shock her heart tomorrow! Is this normal procedure? Safe? and what does it all mean is going on? Thank you Bev I apologize, I am not financially able to pay for this service. Thanks anyway
