Thanks for asking your question on this forum.Heart murmur
is an extra sound heard with stethoscope whilst listening to normal heart sounds
. It is good to know she has got an appointment to see a cardiologist. They would have to do a scan of her heart and find out if there is anything wrong with structure/blood flow in the heart. There are changes in body/heart/lungs in first couple of months and it is quite possible that the murmur is now sounding louder than it appeared before and hence your doctor is requesting a cardiology opinion. I would like to know couple of things:1. Has she been gaining weight?2. Does she get easily tired whilst feeding?3. Does she get lot of sweating?4. Have you noticed any colour changes?Reason for asking these questions is- some heart problems (present since birth, but no manifesting until babies are couple of weeks old) will cause problems with weight gain/feeding etc.
Please do come back to this forum with answers to questions mentioned above.I hope it turns out to be something trivial.Regards Dr Tejas ShahPediatric Intensivist
