Early afterdepolarisations and ventricular arrhythmias in cardiac tissue: a computational study
, 2009 Afterdepolarisations are associated with arrhythmias in the heart, but are difficult to study experimentally. In this study we used a simplified computational model of 1D and 2D cardiac ventricular tissue, where we could control the size of the region ...

Fever Unmasked Brugada Syndrome in Pediatric Patient: A Case Report [PDF]
, 2020 Introduction: Brugada syndrome is an arrhythmogenic disorder that is a known cause of sudden cardiac death. It is characterized by a pattern of ST segment elevation in the precordial leads on an electrocardiogram (EKG) due to a sodium channelopathy.Case ...

Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Electrocardiographic parameters have emerged as valuable noninvasive markers for risk stratification in acute coronary syndrome (ACS). Aims This study aimed to evaluate the correlation between R wave peak time (RWPT) and coronary artery disease (CAD) severity, and to assess its prognostic value for in‐hospital major adverse cardiac ...

Genetic Implications of Fatty Tissue for the Development of Ventricular Arrhythmias
CardiogeneticsVentricular arrhythmias are a common disorder, and sometimes the etiology remains unclear. Present data support cardiac fatty tissue’s potential role as a substrate for ventricular arrhythmias.

Cardiac arrhythmias during long-duration spaceflights
Journal of Arrhythmia, 2014 Few studies have investigated cardiac arrhythmias during spaceflight. Atrial and ventricular premature contractions, short-duration atrial fibrillation, and non-sustained ventricular tachycardia were reported by previous spaceflight programs.

A 10.60 $μ$W 150 GOPS Mixed-Bit-Width Sparse CNN Accelerator for Life-Threatening Ventricular Arrhythmia Detection [PDF]
This paper proposes an ultra-low power, mixed-bit-width sparse convolutional neural network (CNN) accelerator to accelerate ventricular arrhythmia (VA) detection. The chip achieves 50% sparsity in a quantized 1D CNN using a sparse processing element (SPE) architecture.

Drug Testing and Analysis, EarlyView.Regarding cardiovascular effects, DMH decreased vascular reactivity to phenylephrine and acetylcholine. We observed that the combination of DPH and 8‐Cl‐T was identified as the responsible for increasing blood pressure and heart rate in the biological model used.

When the clock strikes: Modeling the relation between circadian rhythms and cardiac arrhythmias [PDF]
arXiv, 2016 It has recently been observed that the occurrence of sudden cardiac death has a close statistical relationship with the time of day, viz., ventricular fibrillation is most likely to occur between 12 am-6 am, with 6 pm-12 am being the next most likely period.

Autopsy findings in cases of fatal COVID‐19 vaccine‐induced myocarditis
ESC Heart Failure, EarlyView.Abstract COVID‐19 vaccines have been linked to myocarditis, which, in some circumstances, can be fatal. This systematic review aims to investigate potential causal links between COVID‐19 vaccines and death from myocarditis using post‐mortem analysis.
