Took LULU Belle to the vet today for followup on bee sting....while taking normal vitals the vet noted her heart rate of only 45 bpm...and a slight arrhythmia...after many tears on my part and xray later it is suspected case of dilated cardiomyopathy. He is NOT an expert cardiologist so is referring us to one...she has been fine up until the bee sting and since then she hasn't had any energy or played with her brothers...she plops down by my side and stays there...my little girl...I never ever expected this...she is only 16 months old....he thinks that it was always an underlying issue and the bee sting stressed her system to the point of us noticing and him hearing...the size of her heart is just a little enlarged not grossly...my baby girl...my heart is breaking for her...
