Multipath joint ablation strategy for focal atrial tachycardia originating from patent foramen ovale: a case report.

Key Laboratory of Birth Defects and Related Diseases of Women and Children of MOE, Department of Pediatrics, West China Second University Hospital, Sichuan University, Chengdu, Sichuan, China.
Introduction: Focal atrial tachycardia (FAT) is predominant in the pediatric population. Recent research has identified cases of sustained FAT originating from the interatrial septum (IAS); a subset of cases presents a unique challenge, with foci originating from the peri-patent foramen ovale (peri-PFO), requiring specialized management during catheter ablation. Here, we present a rare case of peri-PFO-associated FAT that resulted in tachycardia-related cardiomyopathy and propose a comprehensive multipath joint strategy for the successful treatment of PFO-associated FAT.

Accurate detection of cardiac arrhythmias is crucial for preventing premature deaths. The current study employs a dual-stage Discrete Wavelet Transform (DWT) and a median filter to eliminate noise from ECG signals. Subsequently, ECG signals are segmented, and QRS regions are extracted for further preprocessing.

Background: The relationship between premature ventricular contractions (PVC) and right ventricular (RV) function is not widely known. Left ventricular (LV) dysfunction due to PVC is known as PVC-induced cardiomyopathy (PIC) and suppressing the PVC substrate would improve LV function. The effect of PVC ablation on changes in RV function in patients with subtle RV subclinical dysfunction remains unknown.

Sakarya University, Faculty of Medicine, Department of Emergency, Sakarya, Türkiye. Electronic address:
Background: While clinical indicators for synchronized cardioversion in regular supraventricular tachycardias are well-established, their application by prehospital emergency medical services (EMS) still needs to be explored.
Objective: The purpose of this study was to evaluate the factors influencing the decision-making process of prehospital EMS personnel to perform synchronized cardioversion in adults with narrow QRS regular tachyarrhythmias.
Methods: This descriptive study included 598 paramedics actively engaged in prehospital EMS.
