Brief Summary

Arrhythmias of the atria of the heart are a common comorbidity in patients with cardiac rhythm management devices, such as pacemakers and implantable cardioverter/defibrillators (ICD). External electrical cardioversion is an established method to achieve rhythm control (restore normal sinus rhythm) in patients with atrial arrhythmia. Little data on safety and efficacy of external electrical cardioversion in patients with cardiac rhythm management devices exists. Thus, available data on the safety of external electrical cardioversion in cardiac rhythm management patients lacks statistical power to accurately reflect the true hazard of external electrical cardioversion in patients with cardiac rhythm management devices. The aim is to systematically include and follow all patients with cardiac rhythm management devices presenting for external electrical cardioversion, to analyse the effects of external electrical cardioversion on leads and devices.

Outcome Measures

Primary Outcomes (1)

  • Composite safety endpoint: Changes of lead and device parameters

    assessed by device interrogation, if any of the following criteria is met: * a rise in threshold (at constant pulse duration) of \>1V * exit block of any of the pacing leads * loss of programming of the device * rise in shock impedance by 50% * rise in charge time by 50% * drop in battery voltage of ≥0.2V within \< 6 weeks

    2 weeks after CV

Secondary Outcomes (7)

  • Efficacy Endpoint

    within 15 minutes after CV

  • Late changes of lead parameters

    2 weeks after CV

  • Inadvertent induction of ventricular fibrillation

    10 seconds after CV

  • Composite endpoint: Early lead changes

    within 15 minutes after CV

  • Loss of programming

    within 15 minutes after CV

  • +2 more secondary outcomes
