Background: Lumenless leads (LLLs) are widely used for left bundle branch area pacing (LBBAP). Recently, stylet-driven leads (SDLs) have also been used for LBBAP.
Objective: The purpose of this study was to evaluate the acute performance of SDLs during LBBAP in comparison with LLLs.
Cardiac resynchronization therapy (CRT) via biventricular pacing (BiVP-CRT) is considered a mainstay treatment for symptomatic heart failure patients with reduced ejection fraction and wide QRS. However, up to one-third of patients receiving BiVP-CRT are considered non-responders to the therapy. Multiple strategies have been proposed to maximize the percentage of CRT responders including two new physiological pacing modalities that have emerged in recent years: His bundle pacing (HBP) and left bundle branch area pacing (LBBAP).

We sought to compare two different left bundle branch area pacing (LBBAP) implant strategies: the first one accepting LVSP as a procedural endpoint and the second one aiming at achieving LBBP in every patient in spite of evidence of previous LVSP criteria.
Methods: LVSP was accepted as a procedural endpoint in 162 consecutive patients (LVSP strategy group).
Data-Driven Real-Time Magnetic Tracking Applied to Myokinetic Interfaces.
IEEE Trans Biomed Circuits Syst

Article Synopsis
- A new human-machine interface called the myokinetic control interface is proposed for controlling hand prostheses using the movement of multiple magnets placed in residual limb muscles.
- Machine learning models, such as linear and radial basis functions neural networks, are used to improve the localization of these magnets and translate magnetic data into commands for prosthetic devices.
- The system achieved high tracking accuracy (720 μm) and low latency (12.07 μs) in a test environment, and it is designed to be more power-efficient than previous methods, paving the way for future research on managing multiple magnets at once.
Intravenous foreign bodies following trauma to the hand are relatively uncommon with sparse reports of this condition being published in the literature. They have been reported to migrate as far as the thoracic cavity and the heart. In the following case report, we describe a case of an intravenous foreign body following hand trauma, and the treatment and potential complications are also discussed.
