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 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 ...

4. Junctional escape beat - Wikipedia

   en.wikipedia.org/wiki/Junctional_escape_beat

   It is a protective mechanism for the heart, to compensate for the SA node no longer handling the pacemaking activity, and is one of a series of backup sites that can take over pacemaker function when the SA node fails to do so. It can also occur following a premature ventricular contraction or blocked premature atrial contraction. [3]

   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 ...

6. 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 ...

7. Sinoatrial arrest - Wikipedia

   en.wikipedia.org/wiki/Sinoatrial_arrest

   This condition can be detected on an electrocardiogram (ECG) as a brief period of irregular length with no electrical activity before either the sinoatrial node resumes normal pacing, or another pacemaker begins pacing. If a pacemaker other than the sinoatrial node is pacing the heart, this condition is known as an escape rhythm.

   Days later, George revealed in another joint post with The Wanted 2.0 — his and bandmate Siva Kaneswaran's music project and "next chapter" of their popular group — that he had a "2:1 block in ...

9. Heart block - Wikipedia

   en.wikipedia.org/wiki/Heart_block

   Despite the severe-sounding name, heart block may cause no symptoms at all in some cases, or occasional missed heartbeats in other cases (which can cause light-headedness, syncope (fainting), and palpitations), or may require the implantation of an artificial pacemaker, depending upon exactly where in the heart conduction is being impaired and ...
