ECG Cases 29 Misdiagnosis from Lead Misplacement, Artifact and Lead Reversal
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?...
ECG Cases 27 Pericarditis – Diagnosis of Exclusion
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...
ECG Cases 25: ‘Late STEMI’ – How acute is the coronary occlusion?
In this ECG Cases blog we look at 10 patients with potentially ischemic symptoms. Which had a coronary occlusion, and how acute were they? Jesse McLaren explains 'Late STEMI' and how reperfusion strategies should not be based on time of symptom onset...
ECG Cases 24 Reciprocal Change and Occlusion MI
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...
ECG Cases 21: Hyperacute T-waves and Occlusion MI
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....
ECG Cases 18 – ST DEPRESSED Mnemonic and Occlusion MI
In this ECG Cases blog we look at 10 patients who presented with potentially ischemic symptoms and ST depression. Which had occlusion MI?
ECG Cases 17 – ST ELEVATIONS mnemonic and Occlusion MI
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?
