What mechanism that high potassium causes cardiac arrest? I just know high k+ causes hyper excitability of cells?
Cell repolarization: When cardiac muscle cells fire, they use up part of the electrochemical gradient they maintain in life. They are repolarized by an outward potassium (K+) flux across the plasma membrane. This outward K+ current depends on the K+ electrochemical gradient. If the "outside" K+ (in blood & interstitial fluid) is very high, that destroys the K+ electrochemical gradient, the cells can't repol; they stop ...Read more

A 51 year old ex figure skater, who's in good shape had Sudden Cardiac Arrest. Are odds of SCA very low for someone with no known heart abnormalities?
Yes, but never zero.: Known >8 decades: 1/2 of US population has atherosclerosis by later childhood, yet no symptoms for decades: http://goo. Gl/aRhOU2. Symptoms are from plaque ruptures & clots (most without symptoms) yet can close major arteries within minutes: thus SCA with no warning signs in advance; including normal cholesterol & angiogram without problems days prior. Rec: Study my answers & optimize Ds drivers. ...Read more
Is it possible beta blockers could drop heart rate too low and cause cardiac arrest? What would be a concerning heart rate?
Beta Blockers: It is definitely possible for beta blockers to cause the heart rate to drop too low (called bradycardia) but cardiac arrest would be extremely unusual. A low heart rate becomes concerning when someone is having symptoms (such as sweating, dizziness, nausea, etc.) and if it doesn't increase with activity. Some elite athletes have resting heart rates below 40 bpm. ...Read more
Low potassium: You would be better off waiting for your potassium (k) levels to rise before you play soccer. The more important question is, why is your k low? Are you on any medications that would lower it, like diuretics? Do you have a low magnesium level? See a physician to get to the cause of your low k level. It is better to prevent a problem than treat it. ...Read more
I have a low potassium problem and kidney stones problem. Is my hypokalemia the cause of my kidney stones? Or the other way?
Unlikely: A potassium-wasting problem might be due to kidney tubular / parenchymal damage from infection related to kidney stones, but in this case you would have been told of this by your physicians. If your potassium is actually significantly below the healthy range, this is serious and no physician would let it go without a full workup. You have a right to a thorough explanation from your doctor. ...Read more
