Pacemaker dependency after pacemaker implantation.

Cardiology journal, 2007
Pacemaker dependency (PD) can be defined as the risk of serious injury or death from sudden pacemaker failure, an event more dangerous than progressive rate decrease. The aim of this study was to evaluate the incidence of PD during long-term follow-up after pacing system implantation.The study included 3638 patients (mean age 65.3 +/- 10.2 years ...

Two cases of hemodynamic improvement by modulation of atrioventricular delay in cardiac operations

JA Clinical Reports, 2022
Background Symptomatic sick sinus syndrome is one of the indications for pacemaker implantation, and we have to consider to program the pacemaker to an asynchronous pacing mode during an operation. Case presentation We reported two cases with a pacemaker

Irradiation treatment of laryngeal cancer in a patient with an implantable cardioverter-defibrillator (ICD) [PDF]

, 2007
Background: Due to an aging population the incidence of both cardiac and tumor-related illnesses is increasing. A problem may arise if radiotherapy is necessary in close anatomic proximity to an implantable cardioverter-defibrillator (ICD).

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 ...

Subacute Right Ventricle Perforation by Pacemaker Lead Presenting with Left Hemothorax and Shock

Case Reports in Cardiology, 2015
Cardiac perforation by pacemaker is a rare but potentially fatal complication. Acute perforations occurring within twenty-four hours of insertion of pacemaker can lead to hemopericardium, cardiac tamponade, and death.

Induced Pluripotent Stem Cell–Derived Cardiomyocytes Provide In Vivo Biological Pacemaker Function

Circulation: Arrhythmia and Electrophysiology, 2017
Background— Although multiple approaches have been used to create biological pacemakers in animal models, induced pluripotent stem cell–derived cardiomyocytes (iPSC-CMs) have not been investigated for this purpose.

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

Contribution of the circadian pacemaker and the sleep homeostat to sleep propensity, sleep structure, electroencephalographic slow waves, and sleep spindle activity in humans

Journal of Neuroscience, 1995
The role of the endogenous circadian pacemaker in the timing of the sleep-wake cycle and the regulation of the internal structure of sleep, including REM sleep, EEG slow-wave (0.75–4.5 Hz) and sleep spindle activity (12.75–15.0 Hz) was investigated ...
