While most of us have a clear algorithm in our minds for the management of life-threatening hyperkalemia, the same may not be said about the other life-threatening electrolyte abnormalities. In this ECG Cases blog Dr. Jesse MacLaren gives us an approach to potassium, calcium and magnesium abnormalities including risk factor assessment, ECG interpretation and management pearls...
In this month's ECG Cases blog, Dr. Jesse MacLaren guides us through 10 cases of patients whose ECGs show tall T-waves and gives us the tools to distinguish the hyperacute T-waves of occlusion MI from other causes of tall T-waves....
In this ECG Cases we review 10 patients who presented with bradycardia, introduce an approach to reversible causes using the BRADI mnemonic and guide you through how to use the ECG to guide management...
In this ECG Cases blog we look at 10 patients who presented with ST elevation, and review the differential diagnosis of ST elevation using the ELEVATIONS mnemonic. Which had occlusion MI?
In this first part of our 2 part podcast series on AKI we answer questions such as: Is there any value in the BUN:Cr ratio in distinguishing prerenal from intrarenal disease? Why is nephritic syndrome one of the most important intrarenal causes to pick up in the ED? Is there any value in urine electrolytes for the ED workup of AKI? Is there a role for bicarb in patients with severe AKI? How can we choose wisely when it comes to imaging for patients with AKI? How can we utilize POCUS best in working up the patient with AKI? What are the indications for ordering a CK to look for rhabdomyolysis? At what CK level do patients typically develop AKI? How can the McMahon score help us manage rhabdomyolysis? What is the value of urine myoglobin in the workup of rhabdomyolysis? What are indications for dialysis in patients with rhabdomyolysis? What are safe discharge criteria for patients with rhabdomyolysis? and many more...
Which of the following 9 patients had hyperkalemia? Can you estimate how high their serum potassium was based on the ECG? Jesse MacLaren guides us through 9 ECGs underscoring the fact that while the ECG cannot rule out hyperkalemia, significant hyperkalemia often produces ECG changes in the heart rate (bradycardia, junctional rhythm), electrical conduction (PR prolongation or loss of P waves, QRS prolongation, pacemaker delays), and ST/T waves (Brugada phenocopy, peaked T waves that are narrow/pointy) that can be easily recognized. He suggests when you might pull the trigger on giving empiric calcium treatment based on the ECG finding in this month's ECG Cases...
Our new EM Cases feature Rapid Reviews Videos is growing! The latest release covers the main episode on hyperkalemia with Melanie Baimel and Ed Etchells. In the first video Nick Clarridge reviews a general approach to hyperkalemia, the ECG changes and mimics and determining the cause. In the second video he reviews the 3 core principles of hyperkalemia management, the indications for calcium, insulin and bicarb in hyperkalemia and the options in management of hyperkalemia associated with cardiac arrest....
In this month's Best Case Ever on EM Cases Dr. Ross Claybo and Dr. Keerat Grewal tell the story of a patient with a complicated anion gap metabolic acidosis. We discuss how to sort through the differential diagnosis with a better mnemonic than MUDPILES, the controversy around administering sodium bicarbonate for metabolic acidosis, the indications for fomepizole and the value of taking time to to build a therapeutic relationship with your ED patients...
