[/INST] Hello, These Holter findings are not concerning for her age. Anyway, I would recommend performing a cardiac ultrasound in order to examine her heart structure and function and checking thyroid hormone levels for possible thyroid gland dysfunction. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Ilir Sharka, Cardiologist </s>
