What Is a Single Chamber Pacemaker?

Single-chamber pacing is a method of treating bradyarrhythmias by implanting a lead into a cardiac chamber (right atrium or right ventricle) for pacing. According to the pacing mode, it can be divided into solid rate pacing and on-demand pacing. Common clinical ventricular on-demand suppression (VVI) and atrial on-demand suppression (AAI) pacemakers can be used according to the ventricular rate or the atrial rate. Need to pace in time.
