Diagnostic Blind Spot: Physicians Overlook Atrial Fibrillation in Pacemaker‐Dependent Patients

The detection of AF in patients with ventricular-paced rhythm remains a significant diagnostic challenge, with notable gaps even among cardiologists.

Routine interrogation of cardiac devices in cases where the rhythm is unclear can facilitate a timely and accurate diagnosis of this concealed arrhythmia.
