Hello
Thank you for your query at DoctorSpring.com
Your ct angiography report is normal. Your holter doesn't show significant arrhythmias. There doesnt seem to be any worrisome entity here. You should get a 2d echo done. Apart from that nothing more needs to be done if 2d echo is normal.
Feel free to discuss further,
Regards
