Unclear: Serum potassium normals are 3.5 to 5.2, depending on the lab methodology. Levels of over 6 and under 3 will both cause serious consequences; see your doctor for further evaluation if you have abnormal lab values.

Do you mean &gt;: Normal potassium range is 3.5 to 5, the higher you go after that the more likely the heart will stop, at one point it will.

HIgh potassium level: A high level of potassium (k) is not as important as how quickly it got to that high level. Patients with chronic kidney disease can have a k of 6.1 with no symptoms as their hearts are used to a high level of it. A person who is involved in accident and has fast excessive liberation of k, from muscle, can have a cardiac arrest due to an acutely high level of k because his heart is not used to it.
