Cardiac pacing

pacing /pac·ing/ (pās´ing) setting of the pace.

asynchronous pacing cardiac pacing in which impulse generation by the pacemaker occurs at a fixed rate, independent of underlying cardiac activity.

burst pacing overdrive p.

cardiac pacing regulation of the rate of contraction of the heart muscle by an artificial cardiac pacemaker.

coupled pacing a variation of paired pacing in which the patient's natural depolarization serves as the first of the two stimuli, with the second induced by an artificial cardiac pacemaker.

diaphragm pacing , diaphragmatic pacing electrophrenic respiration.

overdrive pacing the process of increasing the heart rate by means of an artificial cardiac pacemaker in order to suppress certain arrhythmias.

paired pacing cardiac pacing in which two impulses are delivered to the heart in close succession, to slow tachyarrythmias and to improve cardiac performance.

ramp pacing cardiac pacing in which stimuli are delivered at a rapid but continually altering rate, either from faster to slower (rate decremental or tune down), from fast to faster (cycle length decremental or ramp up), or in some cyclic combination of increasing and decreasing rates; used to control tachyarrhythmias.

synchronous pacing cardiac pacing in which information about sensed activity in one or more cardiac chambers is used to determine the timing of impulse generation by the pacemaker.

underdrive pacing a method for terminating certain tachycardias by means of slow asynchronous pacing at a rate not an even fraction of the tachycardia rate.

pacing

Etymology: L, passus, step

setting of the heart's rhythm by the sinus node, by another site in the heart, or by an artificial electrical stimulator. Also called atrial pacing, endocardial pacing, sequential pacing, ventricular pacing. See also programmable pacemaker.

pacing [pās´ing]

1. regulation of the rate of a physiologic process, such as by providing timed stimuli.

2. cardiac pacing.

biventricular pacing that in which a lead is used to deliver current directly to the left ventricle, in addition to those used to deliver current to the right atrium and ventricle, so that the ventricles can be induced to pump in synchrony.

cardiac pacing regulation of cardiac rhythm (or the rate of contraction of the heart muscle) with electrical stimuli from a pulse generator or an artificial pacemaker.

diaphragm pacing (diaphragmatic pacing) electrophrenic respiration.

dual chamber pacing control of the heart rate by means of an artificial pacemaker that paces, senses, or does both in the atria and in the ventricles.

phrenic pacing electrophrenic respiration.

single chamber pacing control of the heart rate by an artificial pacemaker that paces and senses in either atria or ventricles, usually in the latter.

transthoracic pacing a system of single or dual chamber epicardial pacing in which the electrode wires are sewn directly onto the epicardium and brought out through an incision in the chest wall. See also epicardial pacemaker.

transvenous pacing a system of single or dual chamber endocardial pacing in which the electrode wires are passed through veins into the right atrium or ventricle. See also transvenous pacemaker.

pacing

1. normal gait of some horses. See pace.

2. stereotyped pacing; a habit in all caged animals, especially if they are active species and are confined in very small areas. May cause excessive wear in footpads, in snakes the damage is usually to the front of the head.

3. setting the pace or rate of movement. See cardiac pacing.
