2. Artificial cardiac pacemaker - Wikipedia

   en.wikipedia.org/wiki/Artificial_cardiac_pacemaker

   The pacemaker generator is a hermetically sealed device containing a power source, usually a lithium battery, a sensing amplifier which processes the electrical manifestation of naturally occurring heart beats as sensed by the heart electrodes, the computer logic for the pacemaker and the output circuitry which delivers the pacing impulse to ...

3. Pacemaker failure - Wikipedia

   en.wikipedia.org/wiki/Pacemaker_failure

   The American Heart Association recommends that the pacemaker be shielded as much as possible, and moved if it lies directly in the radiation field. [7] Short-wave or microwave diathermy uses high-frequency, high-intensity signals. These may bypass pacemaker's noise protection and interfere with or permanently damage the pulse generator. [7]

4. Cardiac pacemaker - Wikipedia

   en.wikipedia.org/wiki/Cardiac_pacemaker

   An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...

   The Wanted vocalist, 36, revealed on Instagram on Saturday, Dec. 21, that he had a pacemaker fitted after announcing weeks earlier that recent tests had found "issues" with his heart.

7. Pacemaker syndrome - Wikipedia

   en.wikipedia.org/wiki/Pacemaker_syndrome

   Individuals with a low heart rate prior to pacemaker implantation are more at risk of developing pacemaker syndrome. Normally the first chamber of the heart (atrium) contracts as the second chamber (ventricle) is relaxed, allowing the ventricle to fill before it contracts and pumps blood out of the heart.

8. Cardiac Pacemakers, Inc. - Wikipedia

   en.wikipedia.org/wiki/Cardiac_Pacemakers,_Inc.

   Cardiac pacemaker's lithium battery-powered pacemaker, the world's first The company's lithium-iodine bipolar pulse generator. CPI designed and manufactured the world's first pacemaker with a lithium anode and a lithium-iodide electrolyte solid-state battery. The pacemaker structure is enclosed in a hermetically sealed metallic enclosure ...

9. Cardiac contractility modulation - Wikipedia

   en.wikipedia.org/wiki/Cardiac_contractility...

   As with conventional pacemaker therapy, the cardiac contractility modulation device cannot be implanted if the leads cannot be positioned appropriately in the heart. In cases where there is an artificial heart valve between the right atrium and ventricle (a mechanical prosthetic tricuspid valve), the valve function could be greatly affected by ...
