I recently had to take my son who's five years old to have his heart checked.Having had a mild illness he started to frequently get blue lips and having listened to his heart through the stethoscope realised that his heart rate was inconsistant and would dip to only 50 B.P.M. for approx. 15 seconds each minute count.With a history of heart disorder in the family we were referred to a specialist.
The ultrasound gave us reassurance in its' findings that there were no mechanical physiological problems i.e.hole in the heart or blockages.
The consultant also prior to ultrasound had carried out a E.C.G.
and explained that sometimes in young children they can have a temporary inconsistant heart rate following illness and often just grow out of it.
