  2. 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 ...

  3. Pacemaker syndrome - Wikipedia

    en.wikipedia.org/wiki/Pacemaker_syndrome

    Cardiology. 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 ...

  4. Atrial fibrillation - Wikipedia

    en.wikipedia.org/wiki/Atrial_fibrillation

    315,000 with atrial flutter (2019) [ 10 ] Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [ 11 ][ 12 ] It often begins as short periods of abnormal beating, which become longer or continuous over time. [ 4 ]

  5. Management of atrial fibrillation - Wikipedia

    en.wikipedia.org/wiki/Management_of_atrial...

    The management of atrial fibrillation (AF) is focused on preventing temporary circulatory instability, stroke and other ischemic events. Control of heart rate and rhythm are principally used to achieve the former, while anticoagulation may be employed to decrease the risk of stroke. [ 1] Within the context of stroke, the discipline may be ...

  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. 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 ...
