Welcome to The Pearl Log — where post-shift wisdom surfaces, one shiny clinical take at a time. Some pearls are fresh, some are rough, all are found under pressure.

Post Cardiac Arrest Management
The AHA has put out a bunch of recent statements and guidelines regarding post cardiac arrest care. Take a look at these to up your game!
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.
A case of palpitations
A 37-year-old with a heart rate just over 200, narrow complexes, and a rhythm so regular it could keep time—no flutter waves in sight. He’s talking, perfusing, and looking at you expectantly. The next move? Something simple, safe, and maybe a little gravity-assisted.
