abnormal ecg

A recent ECG revealed the following:

QRS duration  64 ms

P-R-T axes  76   28   55

What do all of these numbers/results mean?  What should be done about the Abnormal ECG reference?  I am very worried with these results.  Thanks for any help given.

What did your doctor say about your EKG?  What did he/she say as in when to come back for another EKG, or other tests as in an echo.
