Atrial Fibrillation Guideline Check-In

Despite differences across AF guidelines, ED management converges on three principles: initiate DOACs when stroke risk warrants, cardiovert fewer patients but with more attention to duration and risk, and ensure early referral for rhythm-control discussion in newly diagnosed AF. The ED role is less about choosing the “right” guideline and more about safe initiation, thoughtful restraint, and reliable follow-up.

A Scary EKG

You are handed a triage EKG on a young patient with chest pain. The ST elevations are obvious, diffuse, and immediately uncomfortable to look at. Nothing about it feels subtle. The patient is stable, the story is incomplete, and the ECG demands a decision before the labs can help you. Is this an infarct hiding in plain sight, or inflammation pretending to be one? Before you decide, take a closer look at the tracing.

Aslanger Pattern

The Aslanger pattern is an ECG finding in inferior occlusion MI with multivessel disease where competing injury and ischemia vectors prevent classic contiguous ST-elevation. It typically shows isolated ST elevation in lead III, V1 greater than V2, and reciprocal lateral ST depression, and is associated with delayed cath and worse outcomes if missed.

Utility of BNP in Acute HF?

The AHA and the Scientific Statement from the ESC HFA, HFSA, and JHFS both view BNP/NT-proBNP as valuable tests for diagnosing or excluding heart failure and as strong predictors of prognosis. ACEP, however, takes a more ED-focused stance, emphasizing ultrasound over BNP and treating natriuretic peptides as optional adjuncts.
