Refractory hypertensive emergency associated with complete heart block resolved after permanent pacemaker implantation: A case report

Clinical Case Reports, 2022
Severe hypertension sometimes improves with treatment of bradycardia but this phenomenon is under‐reported. Here, an elderly gentleman with complete heart block and a hypertensive emergency was refractory to medical therapies and blood pressure only ...

Current Collector Engineering for New Efficient Bioresorbable Sodium‐Ion Batteries

Advanced Science, EarlyView.
A bioresorbable Na‐ion battery is proposed with Mo or Mg thin‐film current collectors for temporary implants. Mo‐based batteries exhibit superior electrochemical performance and stable cycling compared with Mg counterparts. XPS was used to investigate the Mo/Mg surface oxidation.

Cardiac Resynchronization Therapy and AV Optimization: A Hemodynamic Evaluation with Non-Invasive Techniques

Düzce Tıp Fakültesi Dergisi
Aim: This study aimed to evaluate the impact of atrioventricular (AV) optimization of biventricular pacemakers on cardiac hemodynamic parameters, particularly mitral inflow and aortic valve velocity-time integral (VTI), using impedance cardiography (ICG)

A Dual‐Modal Wearable PPG Smartwatch with AI‐Enhanced Correction for High‐Accuracy and Continuous AF Burden Assessment

Advanced Science, EarlyView.
ABSTRACT Atrial fibrillation (AF) increases the risk of stroke and heart failure, yet accurate quantification of AF burden in daily life remains difficult. Although smartwatch photoplethysmography (PPG) supports continuous monitoring, complex rhythms and signal noise can impair burden estimation.

Comparative outcomes of high-frequency pacing via a guidewire versus an endocardial electrode during transcatheter aortic valve implantation

Consilium Medicum
Background. Rapid ventricular pacing is routinely used during balloon aortic valvuloplasty and transcatheter aortic valve implantation (TAVI). Temporary right ventricular (RV) pacing via a temporary transvenous pacing lead is the standard approach ...

Myocardial threshold in patients with artificial pacemakers [PDF]

The American Journal of Cardiology, 1966
Abstract A method for estimating myocardial threshold in patients with implanted artificial pacemakers has been described. By the external application of a calibrated suppression signal, the output of the implanted unit can be gradually reduced until the myocardial response ceases. The threshold level thus determined can be expressed as a per cent of

Comparison of DeePMD, MTP, GAP, ACE and MACE Machine‐Learned Potentials for Radiation‐Damage Simulations: A User Perspective

Advanced Intelligent Discovery, EarlyView.
The authors evaluated six machine‐learned interatomic potentials for simulating threshold displacement energies and tritium diffusion in LiAlO2 essential for tritium production. Trained on the same density functional theory data and benchmarked against traditional models for accuracy, stability, displacement energies, and cost, Moment Tensor Potential ...

Parametric Analysis of Spiking Neurons in 16 nm Fin Field‐Effect Transistor Technology

Advanced Intelligent Discovery, EarlyView.
Energy efficient computing has driven a shift toward brain‐inspired neuromorphic hardware. This study explores the design of three distinct silicon neuron topologies implemented in 16 nm fin field‐Effect transistor technology. While the Axon‐Hillock design achieves gigahertz throughput, its functional fragility persists. The Morris–Lecar model captures
