2. Transvenous pacing - Wikipedia

   en.wikipedia.org/wiki/Transvenous_pacing

   This means of pacing the heart is not as popular as other means of pacing (like transcutaneous pacing, implanted pacemaker, epicardial pacing) because it is a temporary solution to pace the heart and yet involves a similar level of risk of bleeding as a more permanent solution like placing an implanted pacemaker.

3. Artificial cardiac pacemaker - Wikipedia

   en.wikipedia.org/wiki/Artificial_cardiac_pacemaker

   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. The primary purpose of a pacemaker is to maintain an even heart rate, either because the heart's natural cardiac pacemaker provides an inadequate or irregular heartbeat, or because there is a ...

4. Diastolic depolarization - Wikipedia

   en.wikipedia.org/wiki/Diastolic_depolarization

   The duration of this slow diastolic depolarization (pacemaker phase) thus governs the cardiac chronotropism. It is also important to point out that the modulation of the cardiac rate by the autonomic nervous system also acts on this phase. Sympathetic stimuli induce the acceleration of rate by increasing the slope of the pacemaker phase, while ...

5. 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 ...

6. Pacemaker failure - Wikipedia

   en.wikipedia.org/wiki/Pacemaker_failure

   These factors can contribute to an increased rate of complications which can lead to pacemaker failure. [ 2 ] Approximately 2.25 million pacemakers were implanted in the United States between 1990 and 2002, and of those pacemakers, about 8,834 were removed from patients because of device malfunction most commonly connected to generator ...

   Patients with heart failure are misdiagnosed at a rate of 16% in hospitals and nearly 70% when general practitioners refer patients to specialists, according to a study in the Journal of Cardiac ...

8. Pacemaker potential - Wikipedia

   en.wikipedia.org/wiki/Pacemaker_potential

   In a healthy sinoatrial node (SAN, a complex tissue within the right atrium containing pacemaker cells that normally determine the intrinsic firing rate for the entire heart [3] [4]), the pacemaker potential is the main determinant of the heart rate. Because the pacemaker potential represents the non-contracting time between heart beats , it is ...

   Pacemakers are also sometimes used temporarily when someone is recovering from a heart attack or heart surgery, but in this case only the wires are inserted into the body; the pacemaker box stays ...
