“Can you explain my Holter monitor results please”

Hello I am a 22 year old female. 128 lbs. 5’5 in height. I have been experiencing dizziness, fatigue, chest pain, shortness of breath, and palpitations. I have no prior medical issues. I always have tachycardia when visiting the doctor but with my symptoms recently and heart rate of 170 my doctor gave me a Holter monitor to wear for 5 days. I have the results posted in the photos and just would like someone to clarify what this means and how serious this is. I have anxiety and my doctor didn’t go into any kind of details due to that fact but I don’t want anything sugar coated. I am awaiting for an echo and a cardiologist appointment but it’s gonna be a few weeks and I need answers. Please help. Medication wise I only take Klonopin and birth control.
