HyperkalemiaCreated OnApril 21, 2020Last Updated OnApril 21, 2020byadmin You are here: Main ECG Hyperkalemia < All Topics Table of Contents (serum potassium >5.0 mEq/L) ECG manifestations: Symmetrical, peaked T waves (“arrow head”) Prolonged PR segment Loss of P waves Bizarre QRS complexes Sine wave This ECG displays many of the features of hyperkalemia: Prolonged PR interval. Broad, bizarre QRS complexes — these merges with both the preceding P wave and subsequent T wave. Peaked T waves. This patient had a serum K+ of 9.3 (Warning! In individual patients, the serum potassium level may not correlate closely with the ECG changes. Patients with relatively normal ECGs may still experience sudden hyperkalemic cardiac arrest.) Handy Tips: Suspect hyperkalemia in any patient with a new bradyarrhythmia or AV block, especially patients with renal failure, on hemodialysis or taking any combination of ACE inhibitors, potassium-sparing diuretics and potassium supplements *We do not own this youtube video or ECG, it’s for knowledge sharing purpose
