Overview
An ECG may be helpful in the diagnosis of electrolyte imbalance occurs as a complication of acute tubular necrosis. Appearance of tall and peaked T waves is the early ECG finding of hyperkalemia.
Electrocardiogram
- There are no ECG findings associated with acute tubular necrosis.
- An ECG may be helpful in the diagnosis of complications associated with acute tubular necrosis such as electrolyte imbalance.
- Findings on an ECG suggestive of hyperkalemia include tall and peaked T waves, shortened QT interval, lengthening of PR interval and loss of P waves, and widening of the QRS complex resulting in a sine wave pattern.[1]
- Findings on an ECG suggestive of hypernatremia include sinus tachycardia, QT prolongation, and ST segment deviations.[2]
