Define “physiological pacing.”

Physiological pacing refers to the practice of restoring the heart's natural rhythm and synchronizing its electrical conduction pathways to mimic the innate processes of the heart. This type of pacing aims to enhance the natural coupling of atrial and ventricular contractions, optimizing cardiac output and ensuring that the heart functions in a coordinated manner. By replicating the body's natural signals, physiological pacing often leads to better hemodynamic performance and patient outcomes compared to traditional pacing methods that may disrupt the natural heart rhythm.

This approach focuses on activating the pacemaker sites in a way that respects the complex interplay between the atria and ventricles, which is essential for effective heart function. Through physiological pacing, clinicians can address various forms of heart block or conduction issues while maintaining the heart's inherent synchronization and efficiency.
