What is ECG change seen in Hypokalemia and explain in detail?
Hypokalemia (plasma K+ +-3.5 meq/L). PR interval = 0.2 s; QRS interval = 0.06 s; ST-segment depression. A prominent U wave is now present immediately following the T. Tall T wave is present in hyperkalemiaIf the U wave is erroneously considered a pa of the T, a falsely prolonged QT interval of 0.6 s will be measured in hypokalemia but true QT interval remain same in severe hypokalemia (plasma K+ +-2.5 meq/L)Ref: 23rd Edition of Ganong's Review of Medical Physiology pg no:503
