What Does My ECG Report Indicate?

Question : I was in ER somewhat recently due to a catching, clenching sensation in my chest which I will get sometimes and can be startling and which was occurring a lot. My cardiologist stated this sensation correlated sometimes with PVCs per event recorder monitoring, but that the PVCs occurred only as frequently as in any normal individual. I was wondering about this portion of electrocardiogram from hospital report, since my cardiologist seemed to barely look at the report, and I'm not sure he saw this:

"Possible left atrial enlargement
RSR' or QR pattern in V1 suggests right ventricular conduction delay
Borderline ECG"

Other stats from electrocardiogram:
Ventricular rate: 81 bpm
Atrial rate: 81 bpm
P-R interval: 126 ms
QRS duration: 94 ms
Q-T interval: 356 ms
QTC calculation (Bezet): 413 ms
P Axis: 71 degrees
R axis: 36 degrees
T axis: 47 degrees
Diagnosis: Normal sinus rhythm

I asked an anesthesiologist friend about atrial enlargement and right ventricular conduction delay, and he was saying this is normally benign, but wanted to get a second opinion from this site since I'm paying for subscription.

Thank you so much Dr. Baghdasaryan! I am very obliged for your insights here. A follow up question I would have then would be this: Do you think there could be a correlation between the clenching, catching chest sensation and the ventricular conduction delay, and if so, would it be possibly helpful if my medical team could increase the nerve conduction capacity of my body? I was thinking if there are conduction delays, optimizing conduction could be beneficial, just as for example if one has malabsorption challenges, optimizing absorption would be indicated.
