Benign T-wave Inversion (BTWI) vs. Wellens' • Usually in leads V3-V6 (vs. V2-V4 in Wellens'), but also frequent TWI in inferior leads (II/III/aVF) • Often very distinct J-waves co-existing w/ TWIs - Right-sided precordium often has STE typical of BER • TWI in V4-V6 is preceded by small S-waves & rampant R-waves • TWIs are generally stable over time (vs. ever-evolving T-waves in Wellens') Andrew Sanchez M.D. @ASanchez_PS #Benign #Twave #Inversion #BTWI #EKG #ECG #diagnosis #cardiology #electrocardiogram
