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
Study Arms (3)
Pacemaker patients
Patients with pacemaker, presenting for cardioversion.
ICD patients
Patients with ICD, presenting for cardioversion.
CRT patients
