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?

EM Quick Hits 24 Lateral Canthotomy, Cannabis Poisoning, Hyperthermia, Malignant Otitis Externa, BBB in Occlusion MI, Prone CPR

In this month's EM Quick Hits podcast: Anand Swaminathan on lateral canthotomy, Emily Austin on pediatric cannabis poisoning, Reuben Strayer on an approach to hyperthermia, Brit Long on diagnosis and management of malignant otitis externa, Jesse McLaren on ECG diagnosis of occlusion MI in patients with BBB and Peter Brindley on prone CPR...

ECG Cases 14: Q-wave and Occlusion MI

9 patients presented with potentially ischemic symptoms and Q-waves. Which had Occlusion MI? What is the differential diagnosis of Q-waves? How can one distinguish MI vs LV aneurysm on ECG?...

ECG Cases 13: LVH and Occlusion MI

LVH produces secondary repolarization abnormalities that can mimic STEMI. Signs of occlusion MI in patients with LVH include: new Q waves/loss of R waves, disproportionate and dynamic ST elevation (or ST depression from posterior MI), and hyperacute T waves. In this ECG Cases blog we look at 6 patients who presented with potentially ischemic symptoms and LVH on their ECG. Which had an acute coronary occlusion?
