Key result
The META DDDR pacemaker demonstrated mode switching to VVIR in 57% of patients, showing high sensitivity but low specificity for paroxysmal atrial tachyarrhythmias.

How does the META DDDR pacemaker perform regarding mode switching to VVIR in patients requiring pacing?
The META DDDR pacemaker's mode switching algorithm shows high sensitivity but low specificity for paroxysmal atrial tachyarrhythmias, highlighting the need for careful programming and algorithm refinement.
Vanerio et al. (1991) conducted an observational in Sinus node dysfunction, AV junction ablation, complete or intermittent AV block (n=28). META DDDR pacemaker was evaluated on Mode switching (reversion) to VVIR. The META DDDR pacemaker demonstrated mode switching to VVIR in 57% of patients, showing high sensitivity but low specificity for paroxysmal atrial tachyarrhythmias.
