Overview
An ECG may be helpful in diagnosing complications such as hyperkalemia in the clinical setting of hydronephrosis. Peaked T waves are the earliest sign of hyperkalemia on ECG.
Electrocardiogram
- There are no ECG findings associated with hydronephrosis.
- An ECG may be helpful in the diagnosis of complications associated with hydronephrosis such as hyperkalemia.[1]
- Findings on an ECG suggestive of hyperkalemia include[2][3]
- Tall, Peaked T Waves
- QRS complex widening
- Loss of P Waves
- Sine wave pattern
