Please help! LPFB and LV EF 49

[SunshineSJ]

I had a Stress Test done today and would really appreciate some help trying to understand some results. I have not yet seen they doctor but can see results online.
--------
EKG
Baseline EKG shows sinus tachycardia at a rate of 119, right axis deviation, left posterior fascicular block, poor R-wave progression. PVC's which were multifocal in nature, occasional couplets.

Stress Images
There is a mild decrease in tracer uptake in the inferior wall(s). Also there is a mild decrease in tracer uptake in the apical wall(s).

Borderline TID, clinically corolation suggested.

Left ventricle:
LV EF is calculated at 49%
LV TID is calculated at 1.25

Sum Difference Score (SDS) is calculated at 1.

There is no significant reversible ischemia.
No fixed defect.
--------
Background on me:
27 year old female
117 pounds, 5ft 6in
Recent chest pains, shortness of breath, chest pressure (like elephant on chest) and dizziness.
Stong family history of early heart problems.
Previous EKG showing possible Right Bundle Branch Block
Reoccurring PVC's

At the end of my appointment they told me to follow up with my cardiologist before my next appoint which is scheduled for March 29th.

Thank you in advance!!
