Which EKG findings are associated with hyperkalemia?

• A. Tall peaked T waves and flattened P waves
• B. U waves and wide QRS interval
• C. ST segment elevation and wide QRS interval
• D. Inverted T waves and normal P waves

Answer: (A)

The presence of tall peaked T waves and flattened P waves is indeed characteristic of hyperkalemia on an electrocardiogram (EKG). In hyperkalemia, as potassium levels rise, the myocardium undergoes electrical changes that alter the appearance of the EKG. Tall, peaked T waves are one of the earliest and most commonly recognized signs of elevated potassium levels. These T waves typically become more pronounced and can appear symmetrically peaked as the severity of hyperkalemia increases. In conjunction with the T wave changes, flattened or even absent P waves may also be observed, indicating that the atrial depolarization is affected by the elevated potassium levels. Understanding these specific EKG changes is crucial in a clinical setting, as they can help the clinician identify and manage hyperkalemia promptly, which is essential for preventing potentially life-threatening arrhythmias.
