I have two questions regarding intervals of ECG measurements.

I took an ECG and found interval times of:
.8783 for RR,
.139 for PR
.0575 for QRS
My understanding is that usual values for these would be:
..6 to 1 for RR
..1 to .2 for PR
..09 to .12 for QRS

while the recorded RR and PR are normal from this data, the QRS is very
low, i was wondering what could cause this, or what phisological
implacatins this has (the ventricle contracts very quickly, causes a
longer filling time?)

Also i was wondering if there is a good online source of data on
interval times:

I would like to find PQ and QT times for a normal adult.

Thank you.
