To evaluate the association of anatomical localization with early recurrence during 24-hour telemetry among patients achieving acute electrophysiology laboratory (EP-lab) success, and secondarily with acute EP-lab outcome and target PVC detection in the overall cohort. This retrospective single-center study included 3…

Background: Arrhythmia recurrence after cryoballoon ablation remains a clinically relevant problem in atrial fibrillation (AF). However, factors associated with documented recurrence in low-risk patients without major comorbidities are not well defined. This study aimed to evaluate factors associated with documented a…

Background/Objectives: Arrhythmia recurrence after cryoballoon ablation is commonly linked to persistent atrial fibrillation (AF), atrial enlargement, aging, obesity, inflammation, renal dysfunction, and accumulated cardiovascular comorbidity. Whether these predictors retain their value when the usual systemic risk dr…

Objective: To compare the demographic characteristics and laboratory parameters of children presenting with syncope to the emergency department of a tertiary pediatric hospital in Turkey with those of healthy children evaluated during routine visits, and to assess the diagnostic contribution of commonly ordered labora…

Elektriksel fırtına ile seyreden refrakter ventriküler taşiaritmiler yüksek mortalite ile ilişkilidir ve konservatif tedavilere dirençli olabilir. Stellat gangliyon bloğu algoloji hekimleri tarafından baş ve üst ekstremitenin sempatik kaynaklı ağrılarının tedavisinde sıklıkla kullanılmaktadır. Ventriküler taşikardi te…

Objective: Complete atrioventricular (AV) block complicates management decisions, particularly regarding temporary pacemaker (TP) insertion.Lactate, an anaerobic byproduct, may reflect inadequate cardiac output and help guide this decision.We analyzed the prognostic value of lactate in patients with complete AV block.…

INTRODUCTION: Epicardial access for ventricular tachycardia (VT) ablation is challenging in patients with prior cardiac surgery or dense pericardial adhesions. Although carbon dioxide (CO₂) insufflation has been used to improve visualization, concerns remain regarding its hemodynamic and electrophysiological effects.…

BACKGROUND: Catheter ablation of premature ventricular contractions (PVCs) is an effective treatment modality, but traditionally involves fluoroscopy, which poses radiation risks. Recently, zero-fluoroscopy (ZF) techniques have emerged as a safer alternative, especially in young patients and those requiring multiple p…

We evaluated three multimodal LLMs, ChatGPT (GPT-5.2), Gemini 3, and Microsoft Copilot, in pediatric ECG interpretation, focusing on clinically significant abnormalities and emergency arrhythmias with likelihood ratios as primary outcome measures. This prospective comparative diagnostic accuracy study (STARD/STARD-AI)…

Aim The purpose of this study was to evaluate the clinical course of and therapeutic approaches toward neonatal supraventricular tachycardia (SVT) in the neonatal intensive care unit (NICU). Methods Data on demographic characteristics, clinical course, echocardiographic findings, treatments administered, and treatment…
