heart problem?

After a Friday surgery we were anxiously awaiting the doctors to give us the OK to start chemotherapy that coming up Monday. Monday came and we were ready to do a “standard heart test” that will test the heart to make sure it is ready for chemo. We were told it was nothing to stress about because it is a standard test that 99% of the kids pass and they just do it as a precaution. THANK GOD THEY DO BECAUSE THIS KID FAILED! They came in shortly after and told us his heart was at a 16 and needed to be at a 27! I lost it a little because I finally felt that there was a light at the end of the tunnel and BAM light gone, knocked back down on our butt. I guess because of the tumor, his heart had been over working and the left side was swollen. I asked multiple times if this was a heart problem where he would need surgery, transplant, or additional maintenance and there were positive it was just from the tumor and it would be something that we could control with medicine and eventually wean off the medicine and he would have a normal heart. They rushed him to the cardiac ICU and started heart medicine that can only be administered through that unit. We stay there until the 23 and were happy to be moved back down to our home, the cancer ward. I guess they stabilized his heart enough that he could just go back on a basic heart/blood pressure medicine that the cancer nurses could give him.
