Alright, I only have about a minute to type this.....so forgive it's brevity.
Samuel's EKG came back normal. End of story.
His ECHO results were a little less than perfect - but still good. He does not have pulmonary hypertension (which I've heard numerous horror stories about and I'm immensely thankful that he does not have it) and the left side of his heart looks great. However, he is showing SLIGHT RVH (right ventricular hypertrophy) but according to the nurse, it doesn't look like enough to worry about. Especially since Samuel is off the oxygen almost all day every day now (and it's only slight even with him off the O2 so much.) She said that she would call me back tomorrow if the doctor wanted to make any changes, but thought that he would be pleased with the results.
So all's well. What a great God. :)
