Multiscale studies of delayed afterdepolarizations I: A comparison of two biophysically realistic mathematical models for human ventricular myocytes [PDF]
arXiv, 2023 Focal arrhythmias, which arise from delayed afterdepolarizations (DADs), are observed in various pathophysiological heart conditions; these can lead to sudden cardiac death. A clear understanding of the electrophysiological factors of cardiac myocytes, which lead to DADs, can suggest pharmacological targets that can eliminate DAD-induced arrhythmias ...

An unusual case of sudden cardiac death during sexual intercourse [PDF]
, 2018 The most common cause of sudden death during sexual intercourse in adults is heart disease, and it is usually the male, whereas the death of the woman is unusual. Generally, in these cases, death occurs as a result of cardiovascular disease.

Medications, epilepsy and climate change: Added layers of complexity
British Journal of Clinical Pharmacology, EarlyView.Climate change—the global crisis with pervasive health impacts—has adverse consequences for people with epilepsy (PWE) who have low quality of life due to poor seizure control, socioeconomic disadvantages and comorbidities. This review focuses on the potential effects of climate change on the pharmacological characteristics of antiseizure medications ...

Entanglement Sudden Death in Band Gaps [PDF]
, 2009 Using the pseudomode method, we evaluate exactly time-dependent entanglement for two independent qubits, each coupled to a non-Markovian structured environment. Our results suggest a possible way to control entanglement sudden death by modifying the qubit-pseudomode detuning and the spectrum of the reservoirs.

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT We report the case of a 3‐year‐old asymptomatic girl (12 kg, 96 cm) who was diagnosed with a large iatrogenic left ventricular pseudoaneurysm (LVP) on follow‐up ultrasound, 14 months after apical muscular ventricular septal defect (VSD) closure with a 10 mm Amplatzer Muscular VSD occluder (Abbott, USA) due to device erosion.

Sudden cardiac death – Historical perspectives
Indian Heart Journal, 2014 Sudden cardiac death (SCD) is an unexpected death due to cardiac causes that occurs in a short time period (generally within 1 h of symptom onset) in a person with known or unknown cardiac disease.

Novel Classification of Ischemic Heart Disease Using Artificial Neural Network [PDF]
Computing in Cardiology 2020, 2020 Ischemic heart disease (IHD), particularly in its chronic stable form, is a subtle pathology due to its silent behavior before developing in unstable angina, myocardial infarction or sudden cardiac death. Machine learning techniques applied to parameters extracted form heart rate variability (HRV) signal seem to be a valuable support in the early ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...

Locating Order-Disorder Phase Transition in a Cardiac System [PDF]
Sci Rep 8: 1967, 2018, 2017 To prevent sudden cardiac death, predicting where in the cardiac system an order-disorder phase transition into ventricular fibrillation begins is as important as when it begins. We present a computationally efficient, information-theoretic approach to predicting the locations of wavebreaks that initiate fibrillation in a cardiac system where the order-

A mechanism for electric turbulence in cardiac tissue with optogenetic modification [PDF]
arXiv, 2020 Interruptions in nonlinear wave propagation, commonly referred to as wave breaks, are typical of many complex excitable systems. In the heart they lead to fatal rhythm disorders, the so-called arrhythmias, which are one of the main causes of sudden death in the industrialized world.
