What are the two types of single chamber pacemakers?

The two types of single chamber pacemakers are primarily designed to pace either the atrium or the ventricle. The VVI pacemaker is a common configuration that paces the ventricle and provides sensing capabilities to detect intrinsic ventricular activity, while AAI pacemakers target the atrium and are designed to sense and pace the atrial rhythm.

However, the term "TPS" typically refers to a type of pacemaker utilized in specific contexts, but it is not as universally recognized as the VVI and AAI configurations. Thus, the correct pairing would identify a conventional single-chamber pacing system alongside this specialized device.

Understanding the function of these devices is crucial for recognizing how they interact with the heart’s natural pacing systems and the conditions they are designed to manage. This knowledge is vital for clinicians in making decisions about patient care and managing cardiac arrhythmias.
