Yes your ECG shows early reploraisation syndrome, one thing I would like to ask is whether any of ur family member has history of SCD in younger ages below 50 years, if so u need to consult any cardiologist for appropriate management .
Coming cholesterol yes it is high, but the first treatment if life style and food habits change, if not controlled then u can take medications for it
Next Steps
If history of SCD present take in person cardiologist opinion, for cholesterol part u need change lifestyle modifications , food habits and daily exercise
Health Tips
dont be in hurry to use medications , most of the diseases will be controlled by lifestyle modifications
