pacemaker

1. Anatomy a small area of specialized tissue within the wall of the right atrium of the heart whose spontaneous electrical activity initiates and controls the beat of the heart
2. Med an electronic device for use in certain cases of heart disease to assume the functions of the natural cardiac pacemaker

pacemaker

[′pās‚māk·ər]
(medicine)
A pulsed battery-operated oscillator implanted in the body to deliver electric impulses to the muscles of the lower heart, either at a fixed rate or in response to a sensor that detects when the patient's pulse rate slows or ceases. Also known as cardiac pacemaker; heart pacer.

It has reduced the complications and risks associated with the routine pacemaker by almost 50 percent, like lead infection, pacemaker pocket infection, venous obstruction etc.
Runaway pacemaker may be rarely observed, particularly in the emergency unit.
The researchers used a developmental-biology approach to establish a specific protocol for generating the pacemaker cells.
The Nanostim leadless pacemaker operates like a traditional pacemaker, but is 10 percent the size of a conventional pacemaker and is designed to reduce or eliminate complications associated with leads, chest incisions and surgical pockets.
The Micra and Nanostim can be attached directly to the heart because they are only about one-tenth the size of a conventional pacemaker.
Cantillon is an investigator for the multicenter LEADLESS II study, which is examining the Nanostim[TM] leadless pacemaker.
Theoretically, biological pacemakers, which are composed of electrically active cells that can functionally integrate with the heart, could provide natural heart rhythm regulation without the need for indwelling hardware," says author Vasanth Vedantham, of the University of California, San Francisco.
MATCHING PURR Ian and Snooks both needed a pacemaker.
Now we have pacemakers that are so small - not much larger than an antibiotic pill - that they can be attached directly to the inside of the heart, all the problems related to the old-fashioned pacemaker lead are abolished.
This LEADLESS Pacemaker Observational Study is a prospective, multi-centre, post-market clinical study designed to build additional evidence to support the safety profile of the Nanostim leadless pacemaker in patients indicated for ventricular single chamber pacing.
Pacemaker cells generate electrical activity that spreads to other heart cells in an orderly pattern to create rhythmic muscle contractions.
Objective: To determine the frequency of dual and single chamber pacemaker complications in adults.
