  2. Artificial cardiac pacemaker - Wikipedia

    en.wikipedia.org/wiki/Artificial_cardiac_pacemaker

    A pacemaker may be implanted whilst a person is awake using local anesthetic to numb the skin with or without sedation, or asleep using a general anesthetic. [25] An antibiotic is usually given to reduce the risk of infection. [25] Pacemakers are generally implanted in the front of the chest in the region of the left or right shoulder.

  3. Ventricular assist device - Wikipedia

    en.wikipedia.org/wiki/Ventricular_assist_device

    Infections. Infections in VAD patients occur because the artificial surfaces of the devices serve as a surface for bacterial and or fungal growth. [70] Most infections are classified as driveline infections, which are infections that occur where the device's power cord enters the skin (usually in the upper abdomen) [70]

  4. Implant failure - Wikipedia

    en.wikipedia.org/wiki/Implant_failure

    Causes of pacemaker failure included: lead related failure (lead migration, lead fracture, ventricular perforation), unit malfunction (battery failure or component malfunction), problems at the insertion site (infections, tissue breakdown, battery pack migration), and failures related to exposure to high voltage electricity or high intensity ...

  5. Pacemaker syndrome - Wikipedia

    en.wikipedia.org/wiki/Pacemaker_syndrome

    Pacemaker syndrome is a condition that represents the clinical consequences of suboptimal atrioventricular ... and second is a higher programmed lower rate limit.

  6. Biological pacemaker - Wikipedia

    en.wikipedia.org/wiki/Biological_pacemaker

    Biological pacemakers are indicated for issues such as heart block, slow heart rate, and asynchronous heart ventricle contractions. [2] [3] The biological pacemaker is intended as an alternative to the artificial cardiac pacemaker that has been in human use since the late 1950s.

  7. Cardiac pacemaker - Wikipedia

    en.wikipedia.org/wiki/Cardiac_pacemaker

    It employs pacemaker cells that produce electrical impulses, known as cardiac action potentials, which control the rate of contraction of the cardiac muscle, that is, the heart rate. In most humans, these cells are concentrated in the sinoatrial (SA) node , the primary pacemaker, which regulates the heart’s sinus rhythm .

  8. Pacemaker failure - Wikipedia

    en.wikipedia.org/wiki/Pacemaker_failure

    Pacemaker failure is the inability of an implanted artificial pacemaker to perform its intended function of regulating the beating of the heart. A pacemaker uses electrical impulses delivered by electrodes in order to contract the heart muscles. [ 1 ]

  9. Infection rate - Wikipedia

    en.wikipedia.org/wiki/Infection_rate

    An infection rate or incident rate is the probability or risk of an infection in a population. It is used to measure the frequency of occurrence of new instances of ...
