Case Report: Coexistent Wolff-Parkinson-White Syndrome and Brugada Phenocopy in a Patient With Pneumonia and Myocarditis

open access: yesFrontiers in Cardiovascular Medicine, 2021
Background: In recent years, Wolff-Parkinson-White (WPW) syndrome and Brugada electrocardiogram (ECG) patterns have been reported as coexistent in the same patient. In most cases, the two waveforms appeared separately.

Electrocardiogram of the Mixmaster Universe [PDF]

open access: yes, 2008
The Mixmaster dynamics is revisited in a new light as revealing a series of transitions in the complex scale invariant scalar invariant of the Weyl curvature tensor best represented by the speciality index $\mathcal{S}$, which gives a 4-dimensional ...

Syncope with QT‐interval prolongation and T‐wave inversion in anterior and inferior leads: Foreboder of a life‐threatening condition?

open access: yesAnnals of Noninvasive Electrocardiology, 2023
Even though patients with pulmonary embolism usually present with respiratory distress and tachycardia, the patient presented with syncope only. Typical ECG changes associated with PE include right axis deviation, right bundle‐branch block, S1Q3T3 ...

Focus on pattern recognition receptors to identify prognosis and immune microenvironment in colon cancer

open access: yesFrontiers in Oncology, 2022
In 2011, J. Hoffman, and B. Beutler won the Nobel Prize of medicine for the fact that they discovered the pattern recognition receptors (PRRs) and meanwhile described their effect on cell activation from the innate and adaptive immune systems.
