Examples of overinterpreted AF. (A) Sinus rhythm with multiple premature atrial contractions causing irregular rhythm; interpreted as AF. (B) Sinus arrhythmia with baseline artifacts resembling F waves in a VF lead; interpreted as atrial flutter/AF. (C) Sinus arrhythmia and Wolff‐Parkinson‐White syndrome. Short P‐R interval obscuring P wave, as well as irregular rhythm, contributed to overinterpretation as AF. (D) Advanced second‐degree AV block with junctional escape complexes that led to overinterpretation as AF. Abbreviations: AF, atrial fibrillation; AV, atrioventricular.
