It seems like your son's heart is actually in pretty good shape overall. The findings indicate that the left ventricle, right ventricle, atria, and valves all appear normal. The increased trabeculations in the left ventricle apex could be due to a condition called non-compaction cardiomyopathy, but further evaluation is needed to confirm this. The Holter monitor results showing sinus arrhythmia, junctional beats, and supraventricular ectopics are relatively common in children and may not necessarily indicate a serious issue. It's important to follow up with your pediatric cardiologist for a more detailed discussion and possible further testing, just to be on the safe side.
