asynchronous atrial or ventricular pacing, demand
ventricular pacing, asynchronous, or demand A-V
pace the atrium and ventricles in sequence,
thereby allowing for more atrial contribution to
ventricular filling and normal conduction to
ventricles when the A-V node is conducting
- The dual-chamber generator can be
used as a single-chamber generator; however, dual
chamber asynchronous pacing can be performed.
This pacemaker senses only ventricular activity
but is capable of pacing both the atrium and the
Symptomatic bradycardia; symptomatic bradycardia, and
varying degrees of A-V block in association with acute

A-V sequential pacing does not depend on a functioning AV
conduction system; therefore, there are no absolute
contraindications to its use. In the presence of
