Incidence and patterns of atrial fibrillation after catheter ablation of typical atrial flutter-the FLUTFIB study.

Aims: In patients with atrial flutter (AFL), ablation of the cavotricuspid isthmus (CTI) is a highly effective procedure to prevent AFL recurrence, but atrial fibrillation (AF) may occur during follow-up. The presented FLUTFIB study was designed to identify the exact incidence, duration, timely occurrence, and associated symptoms of AF after CTI ablation using continuous cardiac monitoring via implantable loop recorders.

Methods And Results: One hundred patients with AFL without prior AF diagnosis were included after CTI ablation (mean age 69.

P-wave detection performance of the BioMonitor III, Confirm Rx and Reveal Linq implantable loop recorders.

Introduction: Rhythm interpretation of EGMs recorded by implantable loop recorders (ILRs) is facilitated in cases when p-waves are visible. The three most commonly used ILRs (BioMonitor III, Confirm RX and Reveal Linq) vary in size, electrode placement and filter algorithms. Therefore, p-wave visibility and amplitude on EGM may vary according to the implanted device.

Results from a real-time dosimetry study during left atrial ablations performed with ultra-low dose radiation settings.

Background: Three-dimensional mapping systems and the use of ultra-low dose radiation protocols have supported minimization of radiation dose during left atrial ablation procedures. By using optimal shielding, scattered radiation reaching the operator can be further reduced. This prospective study was designed to determine the remaining operator radiation exposure during left atrial catheter ablations using real-time dosimetry.

Cardiac arrhythmias in patients with COVID-19: Lessons from 2300 telemetric monitoring days on the intensive care unit.

Background: Patients with COVID-19 seem to be prone to the development of arrhythmias. The objective of this trial was to determine the characteristics, clinical significance and therapeutic consequences of these arrhythmias in COVID-19 patients requiring intensive care unit (ICU) treatment.

Methods And Results: A total of 113 consecutive patients (mean age 64.
