| ==Overview==
| |
| Hyperkalemia is an elevated blood level of the [[electrolyte]] [[potassium]] above 5 meq/L. Extreme degrees of hyperkalemia are considered a [[medical emergency]] due to the risk of potentially fatal [[arrhythmia]]s.

| ===History and Symptoms=== | | ===History and Symptoms=== |
| Hyperkalemia often has no symptoms. Occasionally, people may have the following symptoms: irregular heartbeat, nausea, slow, weak, or absent pulse. Extreme degrees of hyperkalemia are considered a [[medical emergency]] due to the risk of potentially fatal [[arrhythmia]]s. A detailed history taking is very helpful in diagnosing the cause of hyperkalemia.
| | |
| ===Physical Examination=== | | ===Physical Examination=== |
| In patients with [[hyperkalemia]], physical examination may vary from normal to [[bradycardia]] ([[heart block]]), [[tachypnea]] due to respiratory muscle weakness and absent [[tendon reflexes]].
| | |
| | ===Laboratory Findings=== |
| | |
| ===Electrocardiogram=== | | ===Electrocardiogram=== |
| Extreme degrees of hyperkalemia are considered a [[medical emergency]] due to the risk of potentially fatal [[arrhythmia]]s. The EKG is an important tool in diagnosing hyperkalemia. However, EKG changes do not always correlate with the degree of hyperkalemia. Some of the EKG changes that can be seen associated with hyperkalemia include [[peaked T waves]] ([[T wave tenting]]), [[PR interval prolongation]], [[QRS complex widening]], absent [[P waves]], a sine wave pattern and [[sinus arrest]].
| | |
| ===Ultrasound=== | | ===X-ray=== |
| In many cases, [[medical ultrasonography|renal ultrasound]] will be performed, since hyperkalemia is highly suggestive of renal failure.
