Study acronym | MOBIPAPA |
Study objectives | A randomised trial to assess the effects of biphasic shocks in combination with an anterior-posterior electrode position and the effect of hand-held shock electrodes on external electrical cardioversion outcome. |
Ethics approval(s) | Not provided at time of registration |
Health condition(s) or problem(s) studied | Atrial fibrillation |
Intervention | With an assumed success rate of the monophasic shock wave form between 79% and 90%, we calculated a group size of 100 patients per group to achieve a statistical power of 0.8 (beta error 0.2) and a two-sided alpha level of 0.05 for each of the two hypotheses. All shocks were delivered in an anterior-posterior electrode position. Patients were anaesthetised using standard procedures (either propofol or etomidate in combination with opioid analgetics). The trial was designed to detect an absolute difference in cardioversion success rate of 10% between two different shock wave forms (monophasic/biphasic) and between two different electrode types (hand-held paddle electrodes/adhesive patch electrodes). Due to training-dependent quality of the positioning of the cardioversion electrodes, a sequential design for the comparison of patch and paddle electrodes was chosen, while the simple exchange of the monophasic and biphasic defibrillators was tested in a randomised design. |

Target number of participants | 200 |
Key inclusion criteria | All patients presenting with persistent atrial fibrillation and an indication for external cardioversion in the Department of Cardiology of the University Hospital Münster, Germany were consecutively screened for the trial. Inclusion criteria: 1. A clinical indication for external cardioversion of atrial fibrillation 2. Documented atrial fibrillation prior to the procedure 3. To minimise thrombo-embolic complications, documented oral anticoagulation with phenprocoumon (international normalised ratio [INR] 2 - 3) for three weeks or exclusion of left atrial thrombi by trans-oesophageal echocardiography directly prior to the cardioversion procedure was required. Continuation of anticoagulation after cardioversion was recommended for all trial patients. |
Key exclusion criteria | Patients presenting with atrial flutter or atrial tachycardias |
