Abnormal EKG. . .normal for me?

[lilypad300]

Last night, I went to the ER.
I was feeling shaky, weak, racing heart & tingly.
I had just had a total thyroidectomy on 8/4 and had some calcium issues.
I thought I was having another low calcium attack.
The doctor ran some blood work and did an EKG.  He said that his diagnosis was stress and anxiety and gave me an ativan.
The EKG showed that there were abnormalities, but the doctor said that the abnormalities were normal for me (how would he know that? I hadn't had an ekg done there before) and that it was nothing to worry about.
Of course I'm freaking out.  Here's what the report says:

So, I have an appointment with the cardiologist Thursday!
Hopefully I'll get some real answers then.

I went to my GP today and saw the nurse practitioner. . .well that was of no real use.  
she told me to take an ativan if i needed it and to see the cardiologist.
i guess i kind of expected that.
she did do another ekg and the results were similar, but she said a bit better. . . .

This is what it reads:

Sinus rhythm
Inferior & anterior T wave changes are borderline abnormal

Borderline ECG

Vent Rate:  99 bpm
P Duration:      84ms
QRS Duration: 96ms
PR Interval:     122ms
QT Interval:     332ms
QTc Interval:   398ms
QT Dispersion:  16ms
P-R-T AXIS:  56, 41, -5

anyone?

If I go to a cardiologist, what should I tell him/her?
What questions should I ask?

thanks!
