Background The Biotronik DX lead is an attractive option due to its floating atrial bipole and its noninferiority compared to dual‐chamber defibrillators. Methods We describe the case of atrial undersensing by the DX lead resulting in failure of the device to appropriately treat a slow ventricular tachycardia. Conclusion This case underlies the importance of understanding the limitations to each lead technology as well as the underlying assumptions inherent to detection enhancement algorithms.
