Question

ECG findings associated with hypokalemia include:

A) U waves and flat T waves.
B) U waves and an Osborn wave.
C) An Osborn wave and a "J" wave.
D) Flattened T waves and a widened QRS complex.

Answer 1

The ECG findings for hypokalemia, which are U waves and flat T waves, are correctly identified in option A. These findings are due to alterations in the heart's normal electrical activity caused by low potassium levels.

Step-by-step explanation:

The ECG findings associated with hypokalemia include U waves and flat T waves, which corresponds to option A) U waves and flat T waves. Hypokalemia, or low potassium levels, leads to cardiac arrhythmias, affecting the heart's normal electrical activity. Important components of the ECG include the P wave, which indicates atrial depolarization, the QRS complex for ventricular depolarization, and the T wave for ventricular repolarization. When potassium levels are low, the T waves can become flatter, and U waves may appear, signifying an alteration in ventricular repolarization. Other findings mentioned, such as an Osborn wave, a "J" wave, and a widened QRS complex, are not typically seen in hypokalemia.
