Refox, Normally, yes. But the amplitude and deflection are subject to change from individual to individual. The deflection isn't necessarily "low" nor is it always positive. It can deflect negatively due to damage from MI or other injury which causes an abnormal pathway through the atria on it's way to the AV node. Misplacement of electrodes will also show a negative deflection though normally you'll see that show up in the QRS as well.

I've had the problem for years. I gave up on water at least a decade ago. Warm, cold, bottled, chugged or sipped...it just gave me a bellyache. I always just figured it was chlorine or chloramine. No matter. For unrelated medical reasons, in 1999 I switched over to Pepsi, first as a way to flush out a PEG, then to dissolve crap in my mouth. The PEG is long gone but the other problem is still present to some extent. And I still drink Pepsi. So, no, you're not alone.

I'm a former cardiology technician, early 90's, and though it's been awhile, I *think* you have it correct. In my world back then I would have perhaps told a patient that because his K+ was high, his heart was "irritable", making him subject to various tachycardias or wide-QRS complex rhythms. The devil may be in the details though, and it's been awhile for me. Someone else may have better information.

I found this little cosmological piece this morning. It seems a nice little logic problem if nothing else: http://www.usapatriotsamerica.com/forum/showthread.php?t=2320
