U wave is a diagnostic term on an electrocardiogram. Under normal circumstances, the electrocardiogram includes P waves, QRS complexes, and T waves. U waves rarely appear after that. Once U waves appear, it indicates certain clinical and pathological significance. Hypokalemia is more common.
Some patients with high calcium are also prone to the appearance and changes of U waves, and when taking digitalis substances and drugs, digitalis poisoning occurs, and U waves can appear on the electrocardiogram. In the diagnosis of electrocardiogram, if the patient finds a U wave, it is necessary to track some clinical information of the patient at this time.
Need to check the electrolyte, the most common is to see if there is hypokalemia and hypercalcemia in the electrolyte. When a patient is found to have hypokalemia, the cause of hypokalemia is physiological, such as reduced food intake, excessive loss, or certain pathological conditions, whether it is kidney tissue or some diseases outside the kidney, including some primary Hypokalemia caused by hyperaldosteronism syndrome and thyroid disease can show U waves on the electrocardiogram to a certain extent.
If U waves are seen on the electrocardiogram, it is necessary to ask whether the patient has taken digitalis substances, and whether there is any poisoning performance of such substances. The above are some clinical problems that need to be considered after U waves appear on the ECG.
