DVI
The DVI mode is
clearly indicated
if
•
AV sequential contraction is necessary due to
symptomatic bradycardia and slow atrial rate, and/or
•
a pacemaker syndrome has already been documented.
The DVI mode is conditionally indicated for
•
frequent supraventricular arrhythmia in which a
combination of pacing and medication has proved
therapeutically effective, and/or
•
the presence of a bradycardia-tachycardia syndrome,
presuming that setting the atrial rate and the AV interval
with or without accompanying medication stops or
prevents supraventricular arrhythmia.
The DVI mode is
contraindicated
for
•
frequent or persistent supraventricular tachyarrhythmia,
including atrial fibrillation or flutter.
Dual Chamber Modes
VDD
The VDD mode is
clearly indicated
for
•
ventricular pacing when adequate atrial rates and
adequate intracavitary complexes are present. The
indication includes the presence of complete AV block
when
1. the atrial contribution is necessary for hemodynamic
optimization, and/or
2. a pacemaker syndrome has already occurred or is
expected.
