Explanation:
Detailed explanation-1: -Very low levels of potassium in the body can lead to irregular heart rhythms, including sinus bradycardia, ventricular tachycardia, and ventricular fibrillation. If a person does not receive treatment, these conditions can be life-threatening.
Detailed explanation-2: -The ‘U’ wave is a wave on an electrocardiogram (ECG). It comes after the T wave of ventricular repolarization and may not always be observed as a result of its small size. ‘U’ waves are thought to represent repolarization of the Purkinje fibers. However, the exact source of the U wave remains unclear.
