Classifying High-Frequency Oscillations by Morphologic Contrast to Background, With Surgical Outcome Correlates.

Purpose: Ictal high-frequency oscillations (HFOs) are a reliable indicator of a seizure onset zone for intracranial EEG recordings. Interictal HFOs often are also observed and may be a useful biomarker to supplement ictal data, but distinguishing pathologic from physiologic HFOs continues to be a challenging task. We present a method of classifying HFOs based on morphologic contrast to the background.

Article Synopsis
- Atrial fibrillation (AF) is a common heart rhythm disorder, and cardioversion is a method used to return the heart to its normal rhythm through medications or electrical shocks.
- The study aimed to evaluate the effectiveness and safety of both pharmacological and electrical cardioversion treatments for AF and related conditions.
- Researchers analyzed data from 112 randomized controlled trials involving nearly 16,000 patients, noting that many trials had a high risk of bias and varying demographics among participants.

Background: Postoperative atrial fibrillation (POAF) is a prevalent complication following cardiac surgery that is associated with increased adverse events. Several guidelines and expert consensus documents have been published addressing the prevention and management of POAF. We aimed to develop an order set to facilitate widespread implementation and adoption of evidence-based practices for POAF following cardiac surgery.

Background: Atrial fibrillation (AF) is one of the most common arrhythmias in clinical practice. Although fat is currently considered to be a risk factor for AF and a pathogenic link between epicardial fat tissue (EFT) and AF has been speculated, there are currently few clinical studies and literature data domestically or abroad.
Objective: This study conducted a meta-analysis of observational case series studies to verify the relationship between atrial fibrillation and EFT and to strengthen the predictive value of EFT in the occurrence, development, and postablative recurrence of AF.
Very early versus early referral for ablation in young patients with newly diagnosed paroxysmal atrial fibrillation.

Background: Catheter ablation (CA) has emerged as an effective therapy for the treatment of paroxysmal atrial fibrillation (AF); however it is unclear whether proceeding expeditiously to CA improves clinical outcomes in a real-world population. This study compares outcomes of CA for new AF within 6 months of diagnosis (very early) 6 to 12 months after diagnosis (early) and 12 to 24 months after diagnosis (later).
Methods: A large nationally-representative sample of patients ages 18 to 64 who underwent CA from January 2011 to June 2019 was studied using the IBM MarketScan Database.
