Journal of Arrhythmia, 2008 Focal atrial tachycardia (AT) is sometimes associated with sick sinus syndrome. A 57-year-old female complained of palpitation, fatigue and presyncope. Ambulatory monitoring demonstrated frequent segments of AT and subsequent sinus arrests.

Energy landscape analysis of cardiac fibrillation wave dynamics using pairwise maximum entropy model [PDF]
arXiv, 2018 Cardiac fibrillation is characterized by chaotic and disintegrated spiral wave dynamics patterns, whereas sinus rhythm shows synchronized excitation patterns. To determine functional correlations among cardiomyocytes during complex fibrillation states, we applied a pairwise maximum entropy model (MEM) to the 2D numerical simulation data of human atrial

Cardiac electrical defects in progeroid mice and Hutchinson-Gilford progeria syndrome patients with nuclear lamina alterations [PDF]
, 2016 Hutchinson–Gilford progeria syndrome (HGPS) is a rare genetic disease caused by defective prelamin A processing, leading to nuclear lamina alterations, severe cardiovascular pathology, and premature death.

Pediatric Dermatology, Volume 42, Issue 2, Page 245-250, March/April 2025.Abstract Background Infantile hemangiomas (IH) affect 2%–10% of the pediatric population. The current standard treatment for complicated IH is oral propranolol. Propranolol initiation protocols vary depending on institution and may occur in an inpatient setting for patients <5‐week‐corrected‐age, with a history of premature birth, and or with low ...

Deciphering Heartbeat Signatures: A Vision Transformer Approach to Explainable Atrial Fibrillation Detection from ECG Signals [PDF]
arXivRemote patient monitoring based on wearable single-lead electrocardiogram (ECG) devices has significant potential for enabling the early detection of heart disease, especially in combination with artificial intelligence (AI) approaches for automated heart disease detection. There have been prior studies applying AI approaches based on deep learning for

Causal Scale Shift Associated with Phase Transition to Human Atrial Fibrillation [PDF]
arXiv, 2018 An example of phase transition in natural complex systems is the qualitative and sudden change in the heart rhythm between sinus rhythm and atrial fibrillation (AF), the most common irregular heart rhythm in humans. While the system behavior is centrally controlled by the behavior of the sinoatrial node in sinus rhythm, the macro-scale collective ...

Pathogenesis of sudden death following water immersion (immersion syndrome) [PDF]
Sympathetic activity under cold stress is investigated. Predominantly vagal cardio-depressive reflexes are discussed besides currently known mechanisms of sudden death after water immersion. Pronounced circulatory centralization in diving animals as well

Screening for QT Prolongation in the Emergency Department: Is There a Better “Rule of Thumb?” [PDF]
, 2020 Introduction: Identification of QT prolongation in the emergency department (ED) is critical for appropriate monitoring, disposition, and treatment of patients at risk for torsades de pointes (TdP).

Experimental Physiology, EarlyView.Abstract Highland populations suffer from significant infant mortality due to chronic ambient hypoxia, which increases the risk of congenital heart disease (CHD) and neonatal pulmonary hypertension. Neither the prevalence of these conditions nor the effectiveness of neonatal cardiac screening to identify CHD or pulmonary hypertension among neonates ...
