What’s the most over-diagnosed tachydysrhythmia? Know your “money lead” and you won’t make that mistake!
Be wary of diagnosing “atrial fibrillation”!
Never trust the ECG machine’s read & look carefully at every single lead!
Both physicians and ECG machines tend to over-call atrial fibrillationThis leads to patients being anticoagulated inappropriately and may cause bad outcomesAlways scrutinize lead V1 (closest to the sinus node) for P-wavesAtrial fibrillation should produce an IRREGULARLY irregular ventricular responseIf the rhythm is REGULARLY irregular and you have grouped or “clumped” beats, consider second degree AV blocks (Mobitz I and Mobitz II)
