Welcome to this concise lecture on EKG changes associated with electrolyte abnormalities. In just a few minutes, we'll explore the key EKG alterations linked to potassium, magnesium, and calcium imbalances, helping you better understand their clinical implications.
Timestamps:
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.
