Delia, I was just wondering. They have me on Cozaar for high BP. I was really tired and had no energy, so I went to my doc and my BP was 168/126. Over the next few months I experienced a very labile BP from 170/110 to 100/60. They still aren't quite sure what to think. I have had a handful of EKG's and two Echos. One ER visit. And so far they have not really come to a reason. In the first Echo I had an enlarged left ventricle, in the next the ventricle was fine, but the aorta was dialated and I had mild diastolic dysfunction. Who knows. The flavor of the month is Pheochromocytoma, because my labs came back funny.
