Single chamber pacing remains a safe, effective, and widely used modality despite interest in dual chamber pacemakers.
Supports selective single-chamber use in appropriate patients; leaves open need for updated comparative trials versus dual-chamber devices.
Although dual chamber pacemakers have held much interest in pacing over the past several years, single chamber pacing remains the modality of choice, worldwide, in the greatest proportion of patients. Atrial or ventricular demand pacing is safe and effective in the majority of patients. In addition, sensors may be used to increase ventricular pacing rate in order to improve cardiac performance.
