Age‐ and sex‐specific modulation of human cardiac electrophysiology by doxorubicin
The Journal of Physiology, EarlyView.Abstract figure legend DOX differentially impacts cardiac electrophysiology based on sex and age. Sex differences were primarily observed among younger hearts, where action potential duration (APD) prolongation was observed in females, but not in males. Created using BioRender. George, S. (2026) https://BioRender.com/wresf1k Abstract Acute doxorubicin (

Journal of Arrhythmia, Volume 42, Issue 4, August 2026.A and B: Right atrial voltage mapping identified a limited region of viable myocardium within an extensive atrial scar. C: Intracardiac echocardiography guided safe deployment of an atrial leadless pacemaker. D and E: Fluoroscopy confirmed stable device positioning in the right atrial appendage of the patient.

BMC AnesthesiologyBackground Remifentanil, an ultra-short-acting µ-opioid receptor agonist, is commonly used for anesthetic management due to excellent adjustability. Remifentanil is known to cause sinus bradycardia, however, because it has a direct negative chronotropic ...

Clinical Case Reports, Volume 14, Issue 7, July 2026.ABSTRACT Transvalvular device leads are undesirable following tricuspid valve replacement. Simultaneous lead extraction and intra‐operative EV‐ICD implantation can provide ongoing defibrillator therapy without crossing the prosthetic valve and may avoid the need for additional pacing hardware when atrioventricular conduction is preserved.

Health Science Reports, Volume 9, Issue 7, July 2026.ABSTRACT Background and Aims Palpitation is one of the commonest presenting complaints to the hospital. The underlying problem may or may not be cardiac. Symptoms may not be present at the time of hospital presentation, and the patient's resting electrocardiogram (ECG) may be normal.

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.Voltage‐gated sodium channels, particularly Nav1.5 encoded by the SCN5A gene, play essential roles in neuronal conduction and cardiac function. Given the widespread use of anaesthetic agents such as ketamine and xylazine in animal studies, this study aimed to evaluate their effects on SCN5A gene expression in pigeon heart tissue.

Annals of Noninvasive Electrocardiology, Volume 31, Issue 4, July 2026.Interpretation of electrocardiograms (ECGs) using an algorithm can improve the detection and diagnosis of atrioventricular blocks in clinical practice. The proposed algorithm, with its high accuracy and structured approach, can help both experienced and less‐experienced healthcare professionals interpret ECGs with more precision, leading to early ...
