  2. Cardiac resynchronization therapy - Wikipedia

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

    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 chest wall.

  3. Cardiac contractility modulation - Wikipedia

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

    A pioneering study had shown that an improved cardiac contractility modulation algorithm could make the therapy an effective treatment for patients with persistent atrial fibrillation. [35] Following these study results the new generation was developed and can now offer cardiac contractility modulation therapy also for patients with atrial ...

  4. Pacemaker syndrome - Wikipedia

    en.wikipedia.org/wiki/Pacemaker_syndrome

    [18] [20] Since its first discovery, there have been many definitions of pacemaker syndrome, and the understanding of the cause of pacemaker syndrome is still under investigation. In a general sense, pacemaker syndrome can be defined as the symptoms associated with right ventricular pacing relieved with the return of A-V and V-V synchrony. [17]

    Results found that pacemaker patients who have no history of atrial tachycardia (AT) or atrial fibrillation (AF), but have device-detected arrhythmias, are approximately 2.5 times more likely to ...

  6. Artificial cardiac pacemaker - Wikipedia

    en.wikipedia.org/wiki/Artificial_cardiac_pacemaker

    Treatment of PMT typically involves reprogramming the pacemaker. [46] Another possible complication is "pacemaker-tracked tachycardia," where a supraventricular tachycardia such as atrial fibrillation or atrial flutter is tracked by the pacemaker and produces beats from a ventricular lead. [47]

  7. Antiarrhythmic agent - Wikipedia

    en.wikipedia.org/wiki/Antiarrhythmic_agent

    They act by blocking the effects of catecholamines at the β 1-adrenergic receptors, thereby decreasing sympathetic activity on the heart, which reduces intracellular cAMP levels and hence reduces Ca 2+ influx. These agents are particularly useful in the treatment of supraventricular tachycardias. They decrease conduction through the AV node.
