overdrive pacing


Also found in: Dictionary, Thesaurus.

fast pacing

A term defined in the context of implantable pacemakers for the delivery—e.g., atrial burst pacing—of rapid, multiple electrical pulses, to pace the heart faster than its intrinsic rate. Fast pacing is used for ventricular tachycardia, to try to break the tachycardia before it progresses to ventricular fibrillation.

overdrive pacing

Using a pacemaker to generate a heart rate that is faster than the spontaneous heart rate of the patient. This is used in attempts to capture and terminate tachycardias or, in some cases, to try to trigger and study tachycardias in patients who have suffered them in the past.

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.
Among the clinical studies presented was the Atrial Dynamic Overdrive Pacing Trial (ADOPT) trial, which demonstrated overall reductions in atrial arrythmia burden for patients utilizing the AF Suppression(TM) pacing algorithm versus those who received conventional DDDR pacing alone.
Carlson will present additional results from the Atrial Dynamic Overdrive Pacing Trial-A (ADOPT-A) study, reviewing the AF Suppression(TM) algorithm's impact on patients with organized atrial tachyarrhythmias.
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).
