My usually very active 14 year old struggled to do an exercise test at school after a virus and antibiotics and was sent for an ECG, which "wasn't completely normal" and then an echocardiogram which showed some trival mitral regurgitation and mild aortic regurgitation but otherwise heart structurally fine. Given the exercise struggle (is legs basically collapsed under him and he had to lie down) the consultant at GOSH has said to come back in 3 weeks and do a stress echo .... googling everything has got me worried and wondered if anyone else had anything like this .... he said the stress echo was precautionary because of the event and to see what the aortic regurgitation was like when the heart was under pressure?? Up to this point I had what I thought was a fit and healthy child ... now I am constantly listening to his breathing and trying not to show I am worried.
