Where does the U wave show up on an ECG?
U waves are usually best seen in the right precordial leads especially V2 and V3. The normal U wave is asymmetric with the ascending limb moving more rapidly than the descending limb (just the opposite of the normal T wave).
What does a large U wave mean?
Prominent U waves are characteristic of hypokalemia (see Chapter 11). Very prominent U waves may also be seen in other settings, for example, in patients taking drugs such as sotalol, or quinidine, or one of the phenothiazines or sometimes after patients have had a cerebrovascular accident.
What fruit has the most electrolytes?
Bananas. Bananas are known to be the king of all potassium containing fruits and veggies. With about 422mg of potassium per banana, we can see why! Potassium helps control muscles and blood pressure.

What does the you wave represent on an ECG?
Kishida H,Cole JS,Surawicz B.
What causes an U wave on an EKG?
Major hypotheses for the origin of the U wave. Repolarization of the His–Purkinje system.
What does an U wave mean on an EKG?
The U wave is thought to reflect the relatively late repolarization process of His-Purkinje cells and certain left ventricular myocytes. It is not always seen on the ECG of normal patients. When present, a normal U wave is of low amplitude (less than one fourth the height of the T wave) and has the same polarity as its T wave.
What does the U wave represent?
The ONSET of the U wave is identified as the first abrupt or gradual deviation from the baseline or the downward slope of the T Wave.
