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...

Ep 155 Treatment of Bradycardia and Bradydysrhythmias

In Part 1 of our 2-part series on bradycardia and bradydysrhythmias we discussed a practical approach with electrophysiologist Paul Dorian and EM doc Tarlan Hedayati. In this, part 2, we discuss details of treatment. We answer questions such as: When should pacing be prioritized over medications and vice versa? What are the latest recommendations about dosing of atropine and when is atropine likely to be detrimental? How is the treatment of bradycardia different in the patient with hypothermia? Cardiac ischemia? Myxedema coma? AV nodal blocker overdose? What are the most common pitfalls in utilizing transcutaneous and transvenous pacing? and many more...

Ep 154: 4-Step Approach to Bradycardia and Bradydysrhythmias

How do we figure out when bradycardia is due to a medical illness and when it is a primary cardiac problem? What are the 4 immediate life threatening diagnosis that we have to entertain and address in the first few minutes of the sick bradycardic patients? What are some key ECG patterns that are sometimes missed by ED docs that can have devastating consequences? How can we better understand Torsades de Pointes by understanding AV blocks? How can we better understand Mobitz l and ll using 'The Dorian' approach? What is BRASH syndrome and how can we recognize it? In this main episode podcast 4-step Approach to Bradycardia and Bradydysrhythmias with electrophysiologist, educator and researcher Dr. Paul Dorian and Chair of Education for the ED at Cook County Hospital Dr. Tarlan Hedayati, we dig deep into bradycardia...
