I will guess a "glitch"... home testing on something as complex as an EKG is problematic - I believe.
I own a couple stethoscopes and an Oximeter (real-time only, gives oxygen saturation and HR in about 10 second samples) and have used them to good result. But, when I confirmed low O2 levels with my Oximeter I didn't jump to any conclusions but did discuss with my primary care on my next annual physical. Or order a over nigh (at home) recording Oximeter test. It confirmed my results and ultimately lead to me suffering from mild obstructive sleep apnea. Sorry if this seems to be off topic, I am just trying to suggest not to jump to conclusions about any DIY reading, but do discuss with your doctor at the earliest convince.
A missing P wave (or very low amplitude) indicates the atrium isn't beating and is a key sign of atrial fibrillation. An unusually high P wave may indicate a PAC, Premature Atrial Contraction...which I believe is usually not important or dangerous. Of course symptoms do vary from person to person. My AFib is almost unnoticed my be when I am physically inactive, the BB and CCB (blockers) I take keep my HR near normal values. I do believe, however, the blocker contribute to my general feeling of fatigue - my old age doesn't help on that issue either.
Good luck, and hope you get some experience base input on DIY EKG.
thank you so much for answering :D
i did mention that i consulted with a doctor if it's a problem but he said no. but he didn't really explain more about the p, t wave and what got me thinking was. why i've never got that pattern before last year but got that quite often lately. and i forgot to mention i got other higher results during the same moment (when i was sick) 130-140 and 140-150bpm.
i also thinking about the machine. should the more sophisticated one helps better.
The hand held ECG's are great for a quick look, but should not be used for serious issues. Depending on how you are holding it, can change "access deviation". I'm sure you are doing it correctly, but T- waves can go flat and/ or disappear all together. I hope your Doctor did at least do a 12 lead on you, if not, they shorted you. You could ask for a "Halter monitor" for a couple weeks, if this is something that has continued on. If you were sick, you could be looking at something as simple as electrolyte imbalances. Blood work would let you know that. I know this post has been up for a while, and hope you got your answers.
