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 16: Poor R-wave progression – The LATE mnemonic
In this ECG Cases blog we examine 6 patients who presented with poor R wave progression, and the LATE mnemonic for the differential...
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...
ECG Cases 9 – First Diagonal Occlusion
Seven patients with ischemic symptoms, none meeting STEMI criteria but all identified by a specific pattern of first diagonal branch occlusion are explored in this ECG Cases blog with Jesse MacLaren who also explains The South African Flag Sign...
ECG cases 7: ST elevation in aVR, STEMI-equivalent?
10 patients presented with the "STEMI-equivalent" ST elevation in aVR with diffuse ST depression. Which had acute coronary occlusion? Jesse McLaren guides us through the differential diagnosis of ST elevation in aVR with diffuse ST depression in this ECG Cases blog...
