Case series of catheter-based arrhythmia ablation in 13 pregnant women.

Background: Catheter ablation is a rarely used procedure to treat arrhythmias during pregnancy.

Hypothesis: In the case of maternal arrhythmia during pregnancy, zero-fluoroscopic catheter ablation is preferable to medical treatment.

Methods: Between April 2014 and September 2021, we examined the demographic data, procedural parameters, and fetal and maternal outcomes in pregnant women undergoing ablation at the Gottsegen National Cardiovascular Center and University of Pécs Medical School, Heart Institute.

New Validated Signal-averaging-based Electrocardiography Method to Determine His-ventricle Interval.

Background/aim: The signal-averaging (SA) technique is used to record high-resolution electrocardiograms (HRECGs) showing cardiac micropotentials. We aimed to develop a non-invasive signal-averaging-based portable bedside device to determine His-ventricle interval.

Patients And Methods: After amplifying the HRECG recordings, signal duration and voltage can be measured up to four decimal precision.

Impact of maternal obesity on the fetal electrocardiogram during labor.

Objective: Maternal obesity affects one in every five women giving birth worldwide. This condition is associated with adverse perinatal outcomes, as well as increased morbidity and mortality for mother and offspring.

Methods: We carried out a prospective study at the University of Pecs Medical Center, Pecs, Hungary, between 1 January 2013 and 1 January 2014.
