Key result
Dual demand pacing using retriggerable refractory periods ('pseudo-mode switching') is reviewed regarding its use, advantages, and limitations for ventricular rate control.
This review details the use, advantages, and limitations of pseudo-mode switching (dual demand pacing) to prevent rapid ventricular pacing during SVT in patients with dual chamber pacemakers.
May guide dual-chamber pacemaker programming during SVT; leaves open prospective outcome trials.
The use of dual chamber pacing in patients with atrioventricular block and paroxysmal supraventricular tachyarrhythmias may present a clinical dilemma because of the rapid and erratic triggering of ventricular pacing. To avoid this, a variety of pacing methods have now been described, including the use of retriggerable atrial refractory periods or dual demand pacing. This review details the use, advantages, and limitations of this poorly understood algorithm referred to as "pseudo-mode switching."

Shenthar et al. (2000) conducted a review in Atrioventricular block and paroxysmal supraventricular tachyarrhythmias. Dual demand pacing using retriggerable refractory periods (pseudo-mode switching) was evaluated. Dual demand pacing using retriggerable refractory periods ('pseudo-mode switching') is reviewed regarding its use, advantages, and limitations for ventricular rate control.
