Brief History of Permanent Cardiac Pacing

Abstract

Depending of which part of the entire conduction system is functionally or structurally damaged, the cardiac pacing can supply the natural pacing and conduction system in a specific way which means that for patients without a preserved atrial function, such as in permanent atrial fibrillation, a solely ventricular pacing could be enough for restoring the cardiac chronotropic function, while for the majority of patient with a preserved atrial function, a sequential atrial and ventricular pacing should be provided, to restore the physiologic chronotropic activity.
