Understanding EKG Changes Due to Electrolyte Abnormalities | NCLEX Review

Welcome to this concise lecture on EKG changes associated with electrolyte abnormalities. We'll explore the key EKG alterations linked to potassium, magnesium, and calcium imbalances, helping you better understand their clinical implications. 00:21 - Potassium: The role of potassium in depolarization and its EKG effects. 00:44 - Hyperkalemia: Wide, flat p-wave, prolonged PR interval, widened QRS complex, and tall, peaked T-Wave. 02:30 - Hypokalemia: Slightly prolonged PR interval, a slightly peaked p-wave, ST depression, and prominent U-wave. 03:56 - Magnesium: The role of magnesium in cardiac electrical activity. 04:13 - Hypermagnesemia: Wide flat p-wave, prolonged PR interval, wide QRS complex, ST depression, and tall T-wave. 05:30 - Hypomagnesemia: Prolonged PR interval and a lengthened QT interval, with Torsades de Pointes ventricular tachycardia risk. 08:29 - Calcium 08:39 - Hypercalcemia: Shortened QT interval and the risk of bradycardia and ventricular fibrillation. 09:11 - Hypocalcemia: Lengthened QT interval and concerns about ventricular tachycardia. This quick review should provide you with a fundamental understanding of EKG changes related to electrolyte imbalances. Remember to like, subscribe, and share this knowledge with your colleagues.
