What is one of the main functions of the AAI pacemaker?

The primary function of the AAI pacemaker is to maintain atrioventricular synchrony. This type of pacemaker is designed to sense electrical activity in the atrium and provide pacing to the atrium when needed. By doing so, it ensures that the atria contract in synchrony with the ventricles, which is crucial for efficient heart function and optimal cardiac output.

The design of the AAI pacemaker allows it to respond only to atrial events while preserving the natural conduction to the ventricles whenever they are functioning properly. This is important because maintaining the natural timing between atrial and ventricular contractions enhances the overall efficiency of the heart, preventing additional complications associated with disorganized heartbeats.

This pacemaker type is particularly useful in settings where bradycardia occurs but the AV conduction system is intact. Thus, through effective atrial pacing, the AAI pacemaker helps maintain the synchrony between the atria and ventricles, promoting stable cardiovascular function.
