QRS Detection in Noisy Electrocardiogram Based on Multi‐Parameter Constrained Stochastic Resonance

IEEJ Transactions on Electrical and Electronic Engineering, Volume 20, Issue 11, Page 1745-1756, November 2025.
One major challenge of QRS wave detection is the deleterious impact of inevitable noise in electrocardiogram (ECG) signals, which can deteriorate the detection performance of algorithms. Previous research has shown a nonlinear monostable potential‐based algorithm for enhancing the QRS complex in a noisy environment. Its main mechanism is the stochastic

Cardiac function and coronary plaque development following masculinizing gender‐affirming hormone therapy: A prospective cohort study

Andrology, Volume 13, Issue 8, Page 2195-2205, November 2025.
Abstract Introduction Myocardial dysfunction and the presence of calcified and non‐calcified coronary plaques are predictors of cardiovascular disease. Masculinizing gender‐affirming hormone therapy may increase cardiovascular risk, highlighting the need for prospective studies to evaluate cardiovascular outcomes during gender‐affirming hormone therapy.

Magnesium Sulfate Combination Therapy for Aconitine‐Induced Electrical Storm

Annals of Noninvasive Electrocardiology, Volume 30, Issue 6, November 2025.
Treatment course of 28 episodes of electrical storm caused by aconitine poisoning with combined magnesium sulfate therapy. ABSTRACT We present the case of a 74‐year‐old man who developed 28 episodes of electrical storm secondary to aconitine poisoning from homemade herbal wine consumption, followed by complete recovery through 28 electrical ...

Electrical Remodeling of Pressure Overloaded Rat Heart Is Attenuated if Imposed During Proliferative Cardiac Growth

Acta Physiologica, Volume 241, Issue 11, November 2025.
ABSTRACT Aim Left ventricular pressure overload (LVPO) in adults is associated with adverse electrical remodeling, characterized by reduced conduction velocity (CV). However, the progression of LVPO differs when imposed during the proliferative phase of cardiac development.
