I'm curious why EKG tracings look different in different people. I mean even in NSR the tracings look very different in different people. I've attached 2 Ekgs here the first is a co-workers and the 2nd is mine. Both are NSR and coincidentally, both are 67bpm/NSR. However, my co-workers looks much cleaner if that makes sense. The T Wave looks much more present and cleaner and their overall ekg tracing looks textbook for the tracings you see for advertisements of heart rate or ekgs. My ekg looks different even though it's NSR and the T wave doesn't look as pronounced. The same thing when done with the Kardia. I'm in no way concerned I'm just more curious as to why EKG tracings look text book in some people and not in others even if both are in NSR? https://www.afibbers.org/forum/read.php?9,200168,200168#msg-200168 Tue, 28 Jul 2026 12:56:23 +0000 Phorum 5.2.23 https://www.afibbers.org/forum/read.php?9,200168,200173#msg-200173 https://www.afibbers.org/forum/read.php?9,200168,200173#msg-200173
When I say there's looks much ''cleaner'' I think I realize why. I just looked at a QRS complex and it looks like the two biggest differences on my Co-workers ekg (which I attached as the first ekg attachment in this thread) reflects a pronounced S wave as well as a T wave that appears mountain shaped. This is probably why I was thinking their ekg looked textbook while my Ekgs from my same watch and kardia don't appear to show much of an S or T Wave.

I just went and looked at my last 12 lead ekg (which I've attached) and that actually appears to show an S wave but still not much of a T wave. That 12 lead also notes non specific ST & T wave abnormality. I remember when I saw that on the EKG my EP wasn't concerned about it at all. So I guess at this point I'm just curious as to why some people would have more pronounced S and or T Waves and If that's better or worse at all?]]> cornerbax AFIBBERS FORUM Thu, 02 Oct 2025 16:24:08 +0000 https://www.afibbers.org/forum/read.php?9,200168,200172#msg-200172 https://www.afibbers.org/forum/read.php?9,200168,200172#msg-200172 Carey AFIBBERS FORUM Thu, 02 Oct 2025 04:53:22 +0000 https://www.afibbers.org/forum/read.php?9,200168,200171#msg-200171 https://www.afibbers.org/forum/read.php?9,200168,200171#msg-200171
I do believe my 12 lead Ekgs look much ''cleaner'' but again I'm sure the look of the 1 lead ekg may vary from person to person.]]> cornerbax AFIBBERS FORUM Thu, 02 Oct 2025 03:35:32 +0000 https://www.afibbers.org/forum/read.php?9,200168,200170#msg-200170 https://www.afibbers.org/forum/read.php?9,200168,200170#msg-200170 Carey AFIBBERS FORUM Thu, 02 Oct 2025 03:13:55 +0000 https://www.afibbers.org/forum/read.php?9,200168,200169#msg-200169 https://www.afibbers.org/forum/read.php?9,200168,200169#msg-200169 The Anti-Fib AFIBBERS FORUM Thu, 02 Oct 2025 03:09:59 +0000 https://www.afibbers.org/forum/read.php?9,200168,200168#msg-200168 https://www.afibbers.org/forum/read.php?9,200168,200168#msg-200168
