2. Pacemaker failure - Wikipedia

   en.wikipedia.org/wiki/Pacemaker_failure

   A pacemaker uses electrical impulses delivered by electrodes in order to contract the heart muscles. [1] Failure of a pacemaker is defined by the requirement of repeat surgical pacemaker-related procedures after the initial implantation. Most implanted pacemakers are dual chambered and have two leads, causing the implantation time to take ...

3. Cardiac contractility modulation - Wikipedia

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

   The FDA approved the OPTIMIZER Smart System, which delivers cardiac contractility modulation therapy, as indicated to improve 6-minute hall walk distance, quality of life, and functional status of NYHA Class III heart failure patients who remain symptomatic despite guideline directed medical therapy, who are in normal sinus rhythm, are not indicated for cardiac resynchronization therapy, and ...

4. Cardiac resynchronization therapy - Wikipedia

   en.wikipedia.org/wiki/Cardiac_resynchronization...

   Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the anterior chest wall.

   The procedure is fairly simple, and can be sometimes done as an outpatient procedure. How long someone will live after getting a pacemaker “really depends on why they needed the pacemaker ...

6. Pacemaker - Wikipedia

   en.wikipedia.org/wiki/Pacemaker

   A pacemaker, also known as an artificial cardiac pacemaker, is an implanted medical device that generates electrical pulses delivered by electrodes to one or more of the chambers of the heart. Each pulse causes the targeted chamber(s) to contract and pump blood, [ 3 ] thus regulating the function of the electrical conduction system of the 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 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 ...
