ECG Cases 51 – Artifact and Lead Misplacement
ECG artifact and lead reversal can mimic tachy-arrhythmia, infarct or Brugada. Learn how to identify these errors to prevent misdiagnosis on this month's ECG Cases with Dr. Jesse McLaren...

ECG Cases 50 – STEMI: A Failed Paradigm, Enter Occlusion MI
Dr. Jesse McLaren illustrates the paradigm shift from STEMI to Occlusion MI (OMI) through 9 cases, and drives home the points that if there is STEMI criteria, consider false positives (eg. secondary and proportional to LVH or BER); if there is no STEMI criteria, consider false negatives and look for other signs of occlusion (eg. acute Q waves or loss of R waves, hyperacute T waves, or reciprocal STD/TWI) and if the ECG is nondiagnostic, consider other OMI signs including clinical (refractory ischemia, hemodynamic/electrical instability) and POCUS (new regional wall motion abnormalities).
ECG Cases 49 – ECG and POCUS for Dyspnea and Chest Pain
In this ECG Cases blog, Jesse McLaren and Rajiv Thavanathan explore how ECG and POCUS complement each other for patients presenting to the emergency department with shortness of breath or chest pain. They explain complementary diagnostic insights into pericardial effusion and cardiac tamponade, occlusion MI and RV strain...
ECG Cases 48 – ECG Interpretation in Cardiac Arrest
In this month's ECG Cases blog Dr. Jesse McLaren reviews interpretation of the pre-arrest ECG: identifying high risk ECGs requiring empiric treatment like calcium for hyperkalemia, magnesium for long QT, or reperfusion for Occlusion MI; the intra-arrest ECG: identifying pseudo-PEA; and post-arrest ECG: the importance of serial ECGs to reduce false positive STEMI, role of POCUS to help with the differential of diffuse ST depression with reciprocal ST elevation in aVR, and identifying signs of Occlusion MI/ false negative STEMI...
