wren <3's echocardiograms....

i apologize for not knowing the technical terms in this post... hope you'll forgive me. i wanted to talk a little bit about wren's echo she had the other day.
it was a little scary. one of the qualifiers for continuing to wean her off the oxygen is the condition of her heart. the pulmonologist explained that when the lungs are damaged, as hers are, that it causes the heart to work extra hard to oxygenate the blood. (this is where i would normally insert the term here _________________) anyway, they had to check her heart and make sure it wasn't overly muscled up.. that it was pretty relaxed and doing it's thing without overworking.
