Resumen
A 31-year-old woman reported dizziness in the early postpartum period after receiving dexmedetomidine. The ECG was misinterpreted as complete heart block; however, more careful analysis revealed an atypical Wenckebach pattern with dual AV nodal conduction and termination of nonconducted P waves with junctional escape beats. The patient's rhythm returned to sinus after stopping dexmedetomidine. Atypical Wenckebach patterns account for greater than 50% of patients with Mobitz Type I AV block and can be misinterpreted as high-grade AV block. This case highlights the causes of atypical Wenckebach patterns and how careful analysis of intervals can help clinicians avoid misdiagnosis.
