I’m tossing a current resting ekg in photos…

Not feeling good today after the diuretics, clearly tachy but that's not out of norm for me.  Trying to determine if I have low k or low magnesium.  I can't find the u waves maybe someone might have insight.

Thanks all!


Not clearly showing signs of either low K or low Mg

No Pot, no T was the mnemonic I learned.  Large T-waves on this ECG.  Low Mg is supposed to produce prolonged PR interval and prolonged QT - neither of which are seen on this trace.

So, as a exercise in trying to document electrolyte imbalance: unhelpful, IMHO.


Low K or low Mg?

Insight- if concerned get your electrolytes measured!

Some of these disturbances can be life threatening.

Best not to wait for your ECG to flat line!!!  Most people can detect that!!!!!

I would hope my defib stops a flatline!

And yes I agree they need to test my levels more frequently.  Many of my current meds are known to cause electrolyte imbalances and it seems my body is highly sensitive to any imbalance.  In the mean time I started taking a calcium supplement and magnesium on top of the potassium I was already taking.  Hoping that will help keep me balanced and prevent my defibrillator from firing. I won't be a happy camper if that starts happening lmao!

You know you're wired when...

Like the Energizer Bunny, you keep going.

I just want to share about the quality of life after my pacemaker, and hopefully increase awareness that lifestyles do not have to be drastically modified just because we are pacemaker recipients.
