Peculiar ST and QT
EMS 12-Lead
by David Didlake
10M ago
David Didlake, FF/EMT-P, AG-ACNP @DidlakeDW An elder female presented to the ED with worsening shortness of breath. She was known to have a history of poorly controlled COPD, AFib, and multivessel coronary disease. Specific to the latter, she was previously deemed not appropriate for CABG (complex rationale) with preference for optimized medical management, instead. A 12 Lead ECG was captured. There is bradycardic Atrial Fibrillation with broad ST-depression in most leads and perceptible ST-elevation in aVR. This should prompt immediate investigation into supply-demand mismatching, or ACS. Bu ..read more

In Review: Lead Placement
EMS 12-Lead
by David Didlake
1y ago
Accurate lead placement is invaluable, and makes a significant impact on appropriate care trajectory, or misdiagnosis with unnecessary utilization of resources. A common finding associated with V1 / V2 malposition is P wave inversion, and rSr’ QRS with T wave inversion -- potentially leading clinicians to suspect Brugada pattern, for example, when no such entity exists. Another spurious finding is a QS pattern that mimics Anterior MI, and in the acute setting this may elicit compulsory urge to pursue invasive coronary intervention that is entirely unwarranted. Tom Bouthillet demonstrates appro ..read more

Lethal Blockade
EMS 12-Lead

1y ago
Acute LAD occlusion in the setting of Right Bundle Branch Block and Left Anterior Fascicular Block. Case Review: https://www.youtube.com/watch?v=0Rs1_TpYMwE Key features of Right Bundle Branch Block: In general, there is no ST elevation throughout the 12 Lead ECG. RBBB has expected slight ST depression, with T wave inversion, in V1-V3 when discordant to a positive R' wave. A possible normal variant is lateral ST elevation (i.e., I/aVL/V5/V6) with bulky T waves when subsequent to a large, slurred S wave. This finding should be assumed new, until proven otherwise, during suspected Acute Corona ..read more
