Which of the following is a potential disadvantage of His Bundle Pacing?

• A. Reduced risk of ventricular capture
• B. V oversensing of A and His signals
• C. Improved myocardial perfusion
• D. Enhanced Left Ventricular Ejection Fraction (LVEF)

Answer: (B)

The potential disadvantage of His Bundle Pacing is the risk of oversensing of atrial and His bundle signals. His Bundle Pacing involves placing the pacing lead near the His bundle area, allowing for more natural conduction of electrical impulses through the heart. However, this proximity to the atrium and the His bundle can lead to oversensing, where the pacemaker detects electrical signals that are not linked to the intended pacing rhythm. This can result in inappropriate inhibition of pacing, causing missed beats or inappropriate therapy. In this context, while His Bundle Pacing has several advantages, such as improved physiological ventricular activation and potentially better cardiac function, the challenge of oversensing is a critical consideration when evaluating the overall effectiveness and reliability of this pacing strategy.
