PET Imaging of Cardiac Inflammation in Viral Myocarditis Using a DPP4‐Targeted Probe

Advanced Science, EarlyView.
This study describes a DPP4‐targeted PET probe for imaging myocardial inflammation by selectively targeting activated immune cells. Derived from the clinically approved small‐molecule inhibitor linagliptin, the probe demonstrates favorable biodistribution with specific cardiac uptake in myocarditis.

ELECTROCAUTERY SELECTION IN PATIENTS WITH CARDIAC PACEMAKER

Urology Research and Practice, 2019
Introduction: Pacemakers have been used to maintain the heart rate when inherent conduction system of the heart fails, either because of disease or surgery. In urologic patients cardiac pacemaker has becoming increased due to advanced age.

Implantation of an S-ICD in a Patient with a DDD Pacemaker and Congenitally Corrected Transposition of the Great Arteries

Cardiovascular Innovations and Applications, 2021
Subcutaneous implantable cardioverter-defibrillator (S-ICD) therapy has become a viable alternative to conventional transvenous ICD implantation. Patients with congenitally corrected transposition of the great arteries (ccTGA) have a high risk of sudden ...

Flecainide Toxicity Leading to Loss of Pacemaker Capture and Cardiac Arrest

JACC: Case Reports, 2021
An 86-year-old man with paroxysmal atrial fibrillation on flecainide, a class IC antiarrhythmic, presented with cardiac arrest. The patient had extremely wide QRS complexes with inconsistent pacemaker capture on electrocardiography.

PVNCRF Neurons Regulate Migraine‐Like Allodynia by Activating CRFR2 on Spinal Trigeminal Caudalis Glutamatergic Neurons

Advanced Science, EarlyView.
Paraventricular CRF neurons in the hypothalamus project to glutamatergic neurons of the spinal trigeminal caudal nucleus, enhancing neuronal activation and CRFR2 signaling. This pathway increases CRF release and excitatory drive, promoting central sensitization and migraine‐related behaviors. Targeting the PVN–SP5C circuit provides a potential strategy

Transdiaphragmatic surgical access by thoracoscopy for epicardial pacemaker implantation in horses [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Cardiac arrhythmias are common in horses and can lead to a decline in performance and sudden death. The use of cardiac pacemakers in horses has been poorly investigated, with a scarcity of description and development of techniques for the device ...

An intracardiac electrogram model to bridge virtual hearts and implantable cardiac devices

, 2017
Virtual heart models have been proposed to enhance the safety of implantable cardiac devices through closed loop validation. To communicate with a virtual heart, devices have been driven by cardiac signals at specific sites.

Electron-conformational transformations in nanoscopic RyR channels govern both the heart's contraction and beating [PDF]

, 2011
We show that a simple biophysically based electron-conformational model of RyR channel is able to explain and describe on equal footing the oscillatory regime of the heart's cell release unit both in sinoatrial node (pacemaker) cells under normal ...

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.
