My 7 week old daughter, who was born five weeks premature has been having issues with hyperkalemia. Her pediatrician and the kidney specialist she had been consulting with order more labs and an ekg at our local childrens hospital. Today I got a voicemail saying that the potassium levels had went down, but all the other labs like the cretin check where abnormal and she was waiting to her from the kidney specialist. She also said that her ekg was abnormal. That both the left and right ventricles were large for her age. She stated that she will also need to see a pediatric cardiologist. I also found out that her dr has laryngitis and will be out for a few days. I was looking for information about both ventricles in the heart of a preemie being larger than normal. Thanks so much!
