Download Lecture Overview
00:00 Here's a 65-year-old diabetic patient with chronic renal failure who's under dialysis therapy but gets sick, fails to come to dialysis for a week because of stomach cramps and diarrhea that developed after eating at a fast food restaurant. 00:16 When she comes finally for her dialysis, they get this ECG. 00:20 What does this ECG show? Notice the pointed T waves that you wouldn't wanna sit on. 00:34 This ECG is diagnostic of hyperkalemia. 00:39 This patient had a serum potassium of 6.9% because they weren't getting dialyzed. 00:45 One of the complications of renal failure is hyperkalemia and one of the things that we do dialysis for is to reduce that serum potassium. 00:53 This patient missed a number of dialysis and consequently, has a serum potassium that's markedly elevated, needs urgent dialysis. 01:02 Thank you very much for being with me for this lecture. 01:06 I look forward to being with you on the next one.
