Key result
Deep learning proposed to detect subtle ventricular oversensing in cardiac devices.
Why the study?
Ventricular oversensing in patients with implantable cardioverter defibrillators and pacemakers is often misclassified and difficult to identify due to subtle episodes and low prevalence.
Does deep learning enable highly sensitive detection of ventricular oversensing in patients with implantable cardioverter defibrillators and permanent pacemakers?
Does deep learning enable highly sensitive detection of ventricular oversensing in patients with implantable cardioverter defibrillators and permanent pacemakers?
Deep learning may offer a highly sensitive approach to identifying ventricular oversensing in CIEDs, addressing the clinical challenge of manually identifying these subtle and time-consuming episodes.

Alerts clinicians to scrutinize NSVT logs for oversensing; leaves open automated detection needs in prospective cohorts.
Ventricular oversensing in patients with implantable cardioverter defibrillators and permanent pacemakers can cause inappropriate shocks or inhibition of pacing and non-physiological oversensing is usually the first manifestation of ventricular lead dysfunction. Ventricular oversensing is often incorrectly logged as non-sustained ventricular tachycardia (NSVT) by cardiac devices, but identifying these episodes is time consuming since some episodes are subtle and the overall prevalence of oversensing is low.

Thiyagarajah et al. (2026) studied Ventricular oversensing in patients with implantable cardioverter defibrillators and permanent pacemakers. Deep learning for detection of ventricular oversensing was evaluated. Deep learning is proposed to identify subtle episodes of ventricular oversensing in cardiac devices, though no quantitative results or specific methods are provided in the abstract.
