What occurs with oversensing of atrial signals in His Bundle Pacing?

Oversensing of atrial signals in His Bundle Pacing can lead to misinterpretation of the heart's electrical activity, which can be mistaken for ventricular tachycardia. This happens because the pacing system might detect an atrial signal that is then misclassified or misinterpreted as a pathologic signal, such as that produced during a rapid ventricular rhythm. Consequently, the pacing device might withhold necessary pacing therapies, believing the patient's heart is functioning normally due to the prevailing atrial signals. This misinterpretation can create significant clinical challenges, as it could prevent the delivery of lifesaving pacing in a patient who might actually require immediate intervention for ventricular conduction problems. The other options describe potential benefits or functionalities that do not align with the implications of oversensing, which highlight the importance of understanding the pacing system's limitations.
