No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
The objective of this study is to evaluate the safety, efficacy and efficiency of rapid anticoagulation reversal with protamine sulfate versus routine activated clotting time (ACT) monitoring in patients undergoing catheter based ablation of atrial fibrillation.
