What are the signs of hyperkalemia?

The signs of hyperkalemia, which is an elevated level of potassium in the blood, include general weakness, arrhythmias, and tall peaked T-waves observable on an electrocardiogram (ECG). Elevated potassium levels can disrupt the normal electrical conduction of the heart, leading to various cardiac arrhythmias, which is a critical indication in patients with hyperkalemia. Additionally, the characteristic tall peaked T-waves are a classic finding associated with hyperkalemia on ECG readings, as increased potassium levels affect the myocardial cells' repolarization processes.

The manifestation of general weakness is also common as high potassium levels can impair muscle function and neurological transmission. Thus, the combination of these signs makes the correct answer a clear representation of the clinical indicators associated with hyperkalemia. Recognizing these signs is crucial for prompt identification and treatment of the condition to prevent serious complications, such as cardiac arrest.
