Hyperkalemia with Peaked T waves on ECG These are the classic peaked T-waves of Hyperkalemia. Notice how they are tall and pointy. They become especially obvious if you can compare them to a baseline ECG. Be able to recognize them and one day you will save a life! - Sam Ghali, M.D. @EM_RESUS #PeakedTWaves #Hyperkalemia #ECG #EKG #Electrocardiogram #Clinical #Cardiology
