DVI Mode
Indications for the DVI Mode
The DVI mode may be indicated for patients with the following conditions:
■
Need for synchronous atrial-ventricular contraction in symptomatic
bradycardia and slow atrial rate.
■
Previously documented pacemaker syndrome.
■
Intermittent supraventricular arrhythmias in which combined pacing
and drugs have been shown to be therapeutically effective.
■
Bradycardia-tachycardia syndrome, provided adjustment of atrial rate
and AV interval terminates or prevents the emergence of
supraventricular arrhythmias with or without concomitant drug
administration.
■
Intermittent atrial and ventricular ectopic arrhythmias.
Contraindications for the DVI Mode
The DVI mode is contraindicated for patients with frequent or persistent
supraventricular tachyarrhythmias, including atrial fibrillation or flutter.
