The DDD pacemaker (dual chamber, dual sensing, dual pacing) most closely replicates the natural conduction of the heart through pacing and sensing both the atria and ventricles. LI pacemaker only paces the left lower chamber, while VVI pacemaker only senses and paces the right lower chamber. VOO pacemaker only paces the ventricles and does not sense any electrical activity in the heart.
