Article Synopsis
- Electrographic flow (EGF) mapping is a technique used to understand how electrical signals move in the heart's atria, especially in relation to atrial fibrillation (AF) compared to normal sinus rhythm (SR).
- The study involved mapping electrical activity in the atria of ten patients, showing that EGF patterns differ significantly in AF, with lower electrographic flow consistency (EGFC) during AF compared to SR, indicating more chaotic activity.
- The findings suggest EGFC could serve as a valuable marker for assessing atrial health and myopathy, correlating with bipolar voltage measurements, which are commonly used to evaluate heart conditions.

Background: We sought to evaluate the anatomic and functional lesion development over time at different atrial sites immediately following delivery of pulsed field ablation (PFA).
Methods: Using a porcine model, PFA ablations were performed in the superior vena cava (SVC), right atrial lateral wall (RA), left atrial appendage (LAA), and right superior pulmonary vein (RSPV) using four different PFA profiles. Mapping was done sequentially in 5-20-min increments up to 280-min post lesion delivery for low voltage area (LVA) assessment and conduction velocity.

Background: Hypertension (HTN) is common in discharged emergency department (ED) patients, yet the short-term outcomes of treating HTN at ED discharge are unclear. This study aimed to investigate whether emergency physician (EP) prescription of oral antihypertensive therapy at ED discharge for hypertensive patients is associated with a decreased 30-day risk of the severe adverse events (AEs), death, and revisits to the ED.
Methods: We conducted an observational cohort study assessing the 30-day outcomes of discharged ED patients with HTN, comparing outcomes based on whether antihypertensive therapy was prescribed.

Background: Out-of-hospital cardiac arrest is a public health crisis affecting about 356,000 adults and 23,000 children annually in the US with 90% fatality. Early bystander CPR and AED application improve survival. Less than 3% of the US population is CPR trained annually.

Helmsley Electrophysiology Center, Department of Cardiology, Icahn School of Medicine at Mount Sinai, New York, New York, USA.
Background: A multielectrode spherical array catheter capable of single-shot mapping and ablation has been introduced.
Objectives: This study sought to compare the efficacy and safety of circumferential, linear, and focal ablation using either microsecond pulsed field (PF) and radiofrequency (RF) ablation in preclinical model.
Methods: Under general anesthesia, a 122 gold-plated multielectrode array was introduced into the left atrium.
