Atrial overdrive pacing had virtually no effect on the average apnea-hypopnea index at 1 month, which rose from 49 at baseline to 49.
The arousal index, desaturation index, and all other variables measured except total sleep time showed improvements with n-CPAP, while atrial overdrive pacing had no measurable effect on the variables, the researchers said.
These algorithms have been introduced whether to prevent AF (Atrial Preference Pacing, Atrial Rate Stabilization, Post Mode Switching Overdrive Pacing
(PMOP)) or to interrupt it (ATP--AntiTachycardic Pacing - burst, ramp, shock).
After 48 hours, half of the patients had their pacemakers programmed for atrial overdrive pacing (AOP), with pacing at a rate greater than 15 beats per minute or greater than their normal nocturnal heart rate.
The failure of AOP to improve symptoms "suggests that overdrive pacing is likely to have a very limited role in this setting," Dr.
Under the HOPE (High Percentage of Overdrive Pacing Evaluation) IDE clinical investigation, BIOTRONIK intends to show safety and efficacy while demonstrating a reduction in the number of AT episodes and improved patient quality of life, so that this important feature may be approved for use in the United States.
My hope is that overdrive pacing with BIOTRONIK's DDD(R)+ device will help this patient's problem," commented Dr.
Dynamic atrial overdrive pacing
decreases symptomatic atrial arrhythmia burden in patients with sinus node dysfunction.
The recently completed multi-center Atrial Dynamic Overdrive Pacing
Trial-A (ADOPT-A)(b) showed AF Suppression provided a reduction in symptomatic AF burden compared to standard DDDR pacing as well as improvements in Quality of Life (QoL).
New Arrhythmia Diagnostics and Monitoring, which provide arrhythmia diagnostic information such as: -- Opposite Chamber Monitoring -- Expanded and selectable EGM -- Initial Interrogation Report -- Tracking of the physiologic atrial rate up to 210 beats-per-minute, to meet the needs of pediatric and active patients -- A new Overdrive Pacing
Algorithm designed to reduce the incidence of atrial tachyarrhythmias following a mode switch episode.
