Wide Complex Tachycardia in a Right-Sided Heart: Diagnostic and Therapeutic Challenges

Dextroposition is a rare cardiac malformation defined as heart shift to right of midline. ECG findings vary with degree of displacement within the chest cavity. We report the second known case of dextroposition with accessory pathway (posteroseptal in our patient), presenting as pre-excited atrial t...

Sumario:Dextroposition is a rare cardiac malformation defined as heart shift to right of midline. ECG findings vary with degree of displacement within the chest cavity. We report the second known case of dextroposition with accessory pathway (posteroseptal in our patient), presenting as pre-excited atrial tachycardia. Abnormal anatomy complicates pathway localization/ablation. (Level of Difficulty: Intermediate.)
