12 lead ECG

ECG 1 hour after PM replacement.  EP may have explained things, but I don't recall (still in LA-LA land)      Anyway:

PR Interval :    *

QRS Duration:  162 ms

QT/QTc: 504/562 ms

P-R-T axes:  *  16   211

Can someone explain these numbers?

Thanks!     --Dave--

...  PR Interval:  Time in milliseconds between leading edge of P wave (Little one that starts the Atria contracting. ) Not given

QT/QTc: 504/562 ms Time in ms between leading edge of Q wave to Leading edge of T wave.  Q is the small drop in shape befoe the gigantic R wave & T is the elevated section following QRS complex.  Criteria is somewhere less than 500 ms. (in the 460 range)  At this point, yours is too long

Can't explain the axis.  Just don;t know

A thirty-day guarantee is not good enough.

I wouldn't be alive if it wasn't for pacemakers. I've had mine for 35+ years. I was fainting all of the time and had flat-lined also. I feel very blessed to live in this time of technology.
