  2. Pacemaker syndrome - Wikipedia

    en.wikipedia.org/wiki/Pacemaker_syndrome

    Pacemaker syndrome is a condition that represents the clinical consequences of suboptimal atrioventricular (AV) synchrony or AV dyssynchrony, regardless of the pacing mode, after pacemaker implantation. [1][2] It is an iatrogenic disease—an adverse effect resulting from medical treatment—that is often underdiagnosed. [1][3] In general, the ...

  3. Pacemaker failure - Wikipedia

    en.wikipedia.org/wiki/Pacemaker_failure

    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] Failure of a pacemaker is defined by the requirement of repeat surgical ...

  4. Artificial cardiac pacemaker - Wikipedia

    en.wikipedia.org/wiki/Artificial_cardiac_pacemaker

    An artificial cardiac pacemaker, commonly referred to as simply a 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 ...

  5. Cardiac contractility modulation - Wikipedia

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

    Cardiac contractility modulation. Cardiac contractility modulation is a therapy which is intended for the treatment of patients with moderate to severe heart failure (NYHA class II–IV) with symptoms despite optimal medical therapy who can benefit from an improvement in cardiac output. The short- and long-term use of this therapy enhances the ...

  6. Implantable cardioverter-defibrillator - Wikipedia

    en.wikipedia.org/wiki/Implantable_cardioverter...

    An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart. The ICD is the first-line treatment and prophylactic therapy for patients at risk for sudden cardiac ...

  7. 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 ...

  8. Cardiac resynchronization therapy - Wikipedia

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

    Cardiac resynchronization therapy. 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 ...

  9. Clinical cardiac electrophysiology - Wikipedia

    en.wikipedia.org/wiki/Clinical_cardiac...

    Clinical cardiac electrophysiology. Clinical cardiac electrophysiology (also referred to as cardiac electrophysiology or simply EP), is a branch of the medical specialty of cardiology concerned with the study and treatment of rhythm disorders of the heart. [1] Cardiologists with expertise in this area are usually referred to as ...
