[Hinews] SEOUL, South Korea — Hanyang University Hospital has implemented pulse field ablation (PFA), an advanced technology for treating atrial fibrillation, completing a series of successful procedures with favorable outcomes, hospital officials announced. Compared to traditional radiofrequency or cryoablation techniques, PFA shortens procedure time and minimizes collateral tissue damage, leading to safer and more efficient treatment.

PFA uses high-intensity electric fields to selectively ablate cardiac cells, significantly reducing the risk of injury structures such as the esophagus and phrenic nerves. This approach enhances safety and shortens recovery periods for patients.

Atrial fibrillation—a common arrhythmia marked by rapid and irregular heartbeats—increases the risk of serious complications such as stroke and heart failure. The condition is increasingly common among individuals over 65, with a growing number of cases reported among those in their 50s.

Under the leadership of Professors Jin-kyu Park and Jin-sun Park at the Arrhythmia Clinic, the team treated several atrial fibrillation patients using the PFA system. Among them were individuals in their 60s and late 70s who had experienced recurrence after prior procedures. All patients were discharged within one to two days post-procedure, with no reported complications.
“Pulse field ablation offers shorter procedure times and a reduced risk of damage to tissues beyond the heart, improving patient safety and quality of life,” said Professor Jin-sun Park. “This technology is expected to set a new standard in arrhythmia management.”

Building on this achievement, Hanyang University Hospital’s cardiology department plans to advance personalized care and integrate innovative technologies to enhance patient-centered treatment for arrhythmias.
