Update

We are just back from Vanderbilt. It seems that his heart has gone back into rhythm. Thank goodness! After his difibulator alerted an abnormal rhythm, we were summoned to Vanderbilt. He had several episodes that were recorded and one lasted longer than 2 hours. Because of the type of episode, the doctor put him back on blood thinner. It seems that his problem was in the top area of the heart. This area is more prone to blood clots so they decided to put him back on the blood thinner. So today he had an ekg and lab work. We go back in six months and they will do an echo to see where we are.
