A Field Guide for Pacing Budget and ROS Constraints [PDF]

arXiv, 2023
Budget pacing is a popular service that has been offered by major internet advertising platforms since their inception. Budget pacing systems seek to optimize advertiser returns subject to budget constraints by smoothly spending advertiser budgets. In the past few years, autobidding products that provide real-time bidding as a service to advertisers ...

Running on empty: Factors underpinning impaired cardiac output reserve in heart failure with preserved ejection fraction

Experimental Physiology, EarlyView.
Abstract Heart failure with preserved ejection fraction (HFpEF) is frequently attributed etiologically to an underlying left ventricular (LV) diastolic dysfunction, although its pathophysiology is far more complex and can exhibit significant variations among patients. This review endeavours to systematically unravel the pathophysiological heterogeneity

Left Bundle Branch Pacing Improved the Outcome of End‐Stage Hypertrophic Cardiomyopathy: A Case Report

Annals of Noninvasive Electrocardiology, Volume 30, Issue 3, May 2025.
ABSTRACT Patients with hypertrophic cardiomyopathy (HCM) enter the terminal stage when developed left ventricle enlargement and ejection fraction (EF) reduction. The concomitant complete left bundle branch block (LBBB) is considered an important factor related to poor outcome. Previous research suggested that biventricular pacing has limited effects on

The Effect of Sacubitril/Valsartan on Supraventricular and Ventricular Arrhythmias in Patients With Heart Failure

Annals of Noninvasive Electrocardiology, Volume 30, Issue 3, May 2025.
Patients undergoing SV therapy had significantly less VTVF events and associated clinical interventions. This effect could lead to less possibility of lethal arrhythmia and sudden cardiac death. ABSTRACT Background Patients with heart failure with reduced ejection fraction (HFrEF) frequently experience electrical disturbances, such as ventricular or ...

A Beating‐Heart Procedure with Soft Robotic Guidance

Advanced Robotics Research, Volume 1, Issue 1, April 2025.
Robot‐assisted pacemaker lead placement through the coronary sinus enabled cardiac pacing in multiple in vivo studies. When compared with conventional clinical tools, the robot reduced procedural time, duration of harmful radiation exposure, and the possibility of tissue damage.

Automatic Mode Switch (AMS) causes less synchronization

Research in Cardiovascular Medicine, 2016
Introduction: Cardiac resynchronization devices are part of modern heart failure management. After implantation, we analyze and program devices in an attempt to ensure their success. Biventricular pacing should be 98% or more for the lowest mortality and

Playing Fast Not Loose: Evaluating team-level pace of play in ice hockey using spatio-temporal possession data [PDF]

arXiv, 2019
Pace of play is an important characteristic in hockey as well as other team sports. We provide the first comprehensive study of pace within the sport of hockey, focusing on how teams and players impact pace in different regions of the ice, and the resultant effect on other aspects of the game.

Left Bundle Branch Pacing in a Patient With Dextroposed Heart: A Case Report

Clinical Case Reports, Volume 13, Issue 4, April 2025.
ABSTRACT The Right Ventricular (RV) apex has been the standard site for pacing in symptomatic bradyarrhythmias, but chronic RV pacing can cause adverse effects such as atrial arrhythmias and left ventricular dysfunction. Physiological pacing, including His bundle and left bundle pacing, offers alternatives with fewer complications. We present a 66‐year‐

A rule-based method to model myocardial fiber orientation in cardiac biventricular geometries with outflow tracts [PDF]

arXiv, 2018
Rule-based methods are often used for assigning fiber orientation to cardiac anatomical models. However, existing methods have been developed using data mostly from the left ventricle. As a consequence, fiber information obtained from rule-based methods often does not match histological data in other areas of the heart such as the right ventricle ...
