In this ECG Cases blog we review 8 cases of patients with prehospital ECGs and explore prehospital ECGs for diagnosing STEMI, Occlusion MI, false STEMI, code STEMI, dynamic ischemic changes, truncated voltages. Can you avoid the pitfalls and spot the pearls that help to make the diagnosis?
Is 15 lead ECG better than 12 lead for diagnosing posterior MI or right ventricular infarction? When do you need a 15 lead ECG? Jesse McLaren guides us through 8 cases to highlight the steps and pitfalls in diagnosing posterior MI and RVMI in light of recent ECG literature...
Computer interpretation of the ECG has been called a double-edged sword: when correct, it increases physician accuracy, but when incorrect it increases errors. This is especially problematic in the emergency department, where computer accuracy drops as clinical significance increases—with common errors for arrhythmias and ischemia. Jesse McLaren guides us through 10 cases where the computer interpretation misguides us and how to avoid these pitfalls...
In this ECG Cases blog we review 10 cases of possible artifact, lead reversal and lead misplacement. Can you spot the abnormalities and avoid the misdiagnosis?...
Jesse McLaren guides us through 9 cases and explains how pericarditis is a diagnosis of exclusion through 3 simple steps: 1. Exclude more serious causes of chest pain, eg wraparound LAD occlusion, inferior OMI 2. Exclude complications of pericarditis, eg myocarditis, large pericardial effusion 3. Exclude normal variant ST elevation presenting with benign chest pain on this month's ECG Cases blog...
In this month's EM Quick Hits podcast: Justin Morgenstern on the evidence for NG tubes in SBO, Jesse MacLaren on recognition of hyperacute T-waves vs other causes of tall T-waves, Brit Long on malignant otitis externa clinical pearls, Salim Rezaie on the value of CCTA in NSTEMI, Justin Morgenstern on the value of CCTA in low-risk chest pain, Hans Rosenberg on how to use the Canadian Syncope Score and it's validation in Canada...
Dr. Jesse MacLaren reviews 10 ECG cases highlighting how reciprocal change can be secondary to LBBB/LVH, primary changes, or both, how it can be the first and remain the dominant sign of occlusion, pointing to subtle ST elevation or hyperacute T waves, how it can can highlight subtle inferior, lateral or proximal LAD occlusions, how it can be the only sign of posterior OMI; and how it can be absent in mid-distal LAD occlusion...
Eight patients presented with potentially ischemic symptoms and T-wave inversions. Which had occlusion MI, which were reperfused and which were reoccluded? Jesse McLaren helps you discover the nuances of Wellens syndrome and T-wave inversions on this month's ECG Cases blog...
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...
