DDD pacing

Also found in: Dictionary, Thesaurus.


(pas'ing) [L. passus, a step]
1. Setting the rate or tempo of an event, esp. the heartbeat. See: pacemaker
2. Walking forward and back or side to side without a defined destination. It is a symptom of anxiety, stress, or of some people affected by dementia.

asynchronous pacing

Cardiac pacing set at a rate independent of the heart's own pacemakers. This allows pacemaking at heart rates that are faster or slower than the patient's diseased pacemaker.

DDD pacing

See: DDD pacemaker

epicardial pacing

Electrical pacing of the heart by conductive leads inserted surgically, usually during bypass graft or valvular operations. The leads are used in the postoperative period for the management of heart blocks or dysrhythmias and are removed as the patient stabilizes.

gastric pacing

Artificial stimulation of gastrointestinal contractions with an implanted pulse generator. It is used to treat gastric motility disorders and morbid obesity.
Synonym: gastric electrical pacing

gastric electrical pacing

Gastric pacing.

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.

synchronous pacing

Cardiac pacing set at a rate matching the underlying rate of one of the heart chambers.

transcutaneous pacing

The application of an electrical current between electrodes placed on the skin to stimulate the heart to beat. Typically, the electrodes are placed on the anterior and posterior chest, or to the right of the sternum and below the clavicle and on the midaxillary line at the level of the sixth to seventh ribs. Also called external pacing, noninvasive pacing, external thoracic pacing, and transchest pacing.
