Radiotherapy‐Induced Side Effects: Epidemiology, Pathogenesis, Prevention and Treatments
Radiotherapy for malignancies frequently injures the organs’ systems through oxidative stress, fibrosis, inflammation, and vascular damage. This review systematically maps the epidemiology, pathogenesis, and emerging therapies to propose a mechanism‑network‑targeted framework for integrated, personalized care in radiation oncology.

Anaesthetic Techniques for Cardiac Ablation—A Scoping Review
ABSTRACT Background Cardiac arrhythmias, particularly atrial fibrillation, have rising prevalence and represent a growing global health burden. Catheter ablation is a commonly used treatment demanding sedation or anaesthesia for comfort, stability and safety. Anaesthetic techniques vary globally, and the optimal strategy has yet to be determined.

Familial sick sinus syndrome in two siblings
Two siblings with sinus node disease are presented. The patients were severely affected and required permanent pacing. A cardiac electrophysiologic study was conducted in Case 2, which revealed an atrioventricular conduction disturbance in ...

ABSTRACT The cardiovascular response to acute exercise is mediated by the autonomic nervous system (ANS) control mechanisms that modulate vascular resistance to support blood pressure and ensure adequate blood flow to active muscles. These autonomic neurocirculatory control mechanisms include a feedforward mechanism, known as central command, and three

Impact of Leadless Pacemaker Implantation Position on Subclinical Right Ventricular Perforation
ABSTRACT Introduction Leadless pacemakers are typically implanted in the mid‐septum of the right ventricle (RV) to mitigate the risk of perforation. However, reports on the precise location of these implants are limited. This study aimed to elucidate tine‐based leadless pacemaker position and presence of subclinical RV perforation through computed ...

QT Interval Evaluation in Right Ventricular Pacing: Validation of a Novel Formula
ABSTRACT Background QT interval measurement in the presence of right ventricular pacing (RVP) represents a clinical challenge. We therefore aimed to derive and validate a formula for QT estimation during RVP in a large cohort of pacemaker patients. Methods and Results We prospectively enrolled 100 patients in a derivation cohort and 487 in a validation
