May favor sequential over VVI pacing to reduce arrhythmia risk; leaves open causal effects pending randomized confirmation.
Does VVI pacing compared to sequential pacing (AAI or DDD) worsen long-term prognosis and complication rates in patients requiring permanent pacemakers?
VVI pacing is associated with a poorer long-term prognosis compared to sequential pacing, particularly due to higher complication rates in patients with ventriculoatrial conduction.
