pacing

 [pās´ing]
1. regulation of the rate of a physiologic process, such as by providing timed stimuli.
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.
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

Cardiology The timing of a physiologic event. See Burst pacing, Demand pacing, DDDR pacing, Dual-chamber pacing, Overdrive pacing, Physiologic pacing, Ramp pacing, Rate responsive pacing, Safety pacing, Transvenous pacing, Underdrive pacing.

pacing

Controlling the rate of an activity, especially the heart rate, usually by electronic devices, such as PACEMAKERS.

A dashboard with the most common pacing profiles during race walking (i.e., even, positive, negative, parabolic, or variable) was prepared and showed to each athlete before the competition.
Nevertheless, roughly 30 per cent of patients do not respond to biventricular pacing treatment, which has been shown to improve survival in clinical trials.
However, despite knowledge of pacing strategies, athletes typically make poor pacing decisions.
MultiPoint Pacing technology is designed to deliver electrical pulses to multiple locations on the Quartet lead to make the heart's lower chambers pump in a more coordinated way to mirror the natural contractions of a healthy heart.
"These new data add to the growing body of evidence supporting the use of BiV pacing for treating patients who have AV block and left ventricular dysfunction who are indicated under current clinical guidelines for permanent RV pacing with a pacemaker," said Anne B.
According to the company, MultiPoint pacing provides the ability to deliver two left ventricular (LV) pacing pulses, either simultaneously or sequentially, rather than the standard single pulse for each pacing cycle (heartbeat).
Conclusion: Right ventricular outflow tract pacing site is safe and pacing impedance and threshold values are comparable with conventional RVA pacing in the long-term.
From a mean baseline of 263 meters, the distance covered improved by 82 meters in the biventricular-pacing group, significantly greater than the 57-meter improvement observed in the right ventricular pacing group.
Although in most cases you should stay with your pacing plan, occasionally the weather or other circumstances may merit slight changes in your strategy.
To apply timing, pacing and sequencing, the services of an experienced instructional designer were secured.
What are the benefits of physiological pacing? In patients with complete heart block, physiological pacing improves a number of haemodynamic parameters.
