ECG Cases 39 – Transient STEMI Pitfalls and Pearls

In this ECG Cases blog we look at 9 patients with possible transient STEMI and discuss pitfalls and pearls in ECG interpretation and management...

ECG Cases 30 Beware Computer Interpretation Errors

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...

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 26: Pulmonary Embolism and Acute RV Strain

In this month's ECG Cases Dr. Jesse McLaren runs through 10 cases and explains how the ECG can be integral in the diagnosis and management of pulmonary embolism, even though it is not incorporated into any of the commonly used decision tools for diagnosis of pulmonary embolism...

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 22: T-wave INVERSION mnemonic

The differential for T-wave INVERSION includes: Incorrect lead placement, No bundle (RBBB, LBBB), Ventricular hypertrophy (LVH, RVH), Embolism, Reciprocal/refractory/reperfused occlusion MI, Sudden death (ARVD), Iatrogenic (digoxin), Obtunded (eg SAH), and Normal variant. Jesse McLaren runs through 10 cases of patients who present to the ED who have T-wave inversions on their ECGs...

ECG Cases 19 Tachycardias – Approach, WIDER Mnemonic for Wide SVT DDx, VT vs SVT

In this ECG Cases blog Jesse McLaren review an approach to tachycardia, explore the WIDER mnemonic for wide SVT differential diagnosis, and how to distinguish VT from SVT with 10 cases...

ECG Cases 8 Cardiovascular Emergencies During The COVID-19 Pandemic

In this ECG Cases blog we look at 6 patients who presented with cardiorespiratory symptoms, possibly from COVID and illustrate the dangers of anchoring, being hypervigilant for cardiovascular complications, and why testing for COVID in patients being admitted for ACS is important...
