Double chamber cross‐talk, the ultimate double‐cross
Key result
Programming changes resolve unusual double cross-talk in a dual-chamber ICD case.
- n=1
Why the study?
Far-field ventricular events are commonly sensed in the atrial channel, but the reverse is uncommon and observing cross-talk in both chambers simultaneously had never been reported.
Population
A case of a patient with a dual-chamber Medtronic implantable cardioverter-defibrillator

Almehmadi et al. (2020) conducted a case report in Double cross-talk in a dual-chamber implantable cardioverter-defibrillator (n=1). Programming changes was evaluated on Resolution of double cross-talk. Programming changes successfully resolved an unusual case of double cross-talk in a dual-chamber Medtronic implantable cardioverter-defibrillator.
