Re: Question about abnormal EKG and low Potassium
Pam, don't worry; the thallium stress test is a very good test and it will show up any congestive heart problems or arterial blockage.
An ECG interpretation is really what separates the men from the boys and you should rely on your cardiologist's interpretation. Usually a GP will shake his head knowingly when all he really sees are the same "squiggly lines" you do.
As far as the estimate that the irregular ECG was due to "low potassium", that just plain guesswork. If your serum potassium level goes low on a diuretic you have to either supplement the potassium, usually by diet, or switch away from the drug, ESPECIALLY if you have weakness symptoms from the low K+.
I think EVERYBODY'S serum potassium goes slightly low from most common diuretics. It's just the way they WORK. (Nearly all the potassium in the body is in the cells, so too much can be made of low serum potassium. However, if you get LOW SODIUM, you've got a BIG, BIG problem.)
Good luck with the stress test.
