Interesting ECG (3)

Since some of the students were kinda confused about how WPW (Wolff-Parkinson-White) syndrome ECG looks like - so coincidentally I just came across one last night!

Looking at the above ECG, delta waves (the slurred upstroke) can be seen in every beats, broadening the ventricular complex as well as shortening the PR interval. Very typical!

ooo can see the widened QRS complexes...

but just wondering, the baseline seemed a bit shaky? as in no one line wic they return to?

wah recently u showed us so many ecg Questions! sigh i wonder when only i can be as 'geng' as u.. *salute*

Oh it's not the baseline problem. They are ST depressions.
WPW is one of the non-ischemic causes of ST depressions, due to the conduction abnormality=)

And ya it seems that I came across quite some interesting ECGs in ER lately!;)

Ya, some prominent delta wave can easily seen.

But some are really hard to see.

oh.. i didnt know that WPW has ST depression.. i thought only due to cardiac ischemia..

looks like i hv a lot to learn =/
