Cryothermal Energy Ablation Of Cardiac Arrhythmias 2005: State Of The Art [PDF]
At the time of antiarrhythmic surgery, cryothermal energy application by a hand-held probe was used to complement dissections and resections and permanently abolish the arrhythmogenic substrate.

The Phospholamban (PLN) R9C mutation reduces SERCA2a binding, increasing calcium recycling and baseline contractility. However, the excess of free PLN promotes pentamer formation, limiting phosphorylation and blunting β‐adrenergic signaling. Under cardiac stress, enhanced functional demands overwhelm proteostasis in PLN R9C cells, leading to misfolded ...

PEDOT:PSS—A Key Material for Bioelectronics
PEDOT:PSS ‐ Poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate ‐ is typically processed from water dispersions to form multifunctional and multidimensional constructs with tunable electronic and ionic conductivity. Throught processing engineering, PEDOT:PSS is intergrated in bioelectronic devices that operate efficiently in physiological conditions

Incidence and severity of arrhythmias and conduction disturbance after repair of tetralogy of Fallot
Ventricular and supraventricular arrhythmias and conduction disturbances were evaluated by routine electrocardiography and 24-hour ambulatory monitoring in 31 patients who underwent correction of tetralogy of Fallot. The interval from operation to

Recent advances in the management of ventricular tachyarrhythmias [version 1; referees: 2 approved]
Ventricular arrhythmias are an important cause of cardiovascular morbidity and mortality, particularly in those with structural heart disease, inherited cardiomyopathies, and channelopathies. The goals of ventricular arrhythmia management include symptom

Andersen-Tawil syndrome (ATS) is a rare condition consisting of ventricular arrhythmias, periodic paralysis, and dysmorphic features. In 2001, mutations in KCNJ2, which encodes the α subunit of the potassium channel Kir2.1, were identified in patients ...

A super‐conductive ionic patch reprograms the post‐infarction microenvironment by enabling stable ionic migration and electrical signal transmission within damaged myocardium. The patch rapidly adheres to cardiac tissue, enhances conduction velocity, suppresses excitation‐contraction decoupling, and promotes structural and functional cardiac repair in ...

A comparative study of early afterdepolarization-mediated fibrillation in two mathematical models for human ventricular cells [PDF]
Early afterdepolarizations (EADs), which are abnormal oscillations of the membrane potential at the plateau phase of an action potential, are implicated in the development of cardiac arrhythmias like Torsade de Pointes.

Bidirectional ventricular tachycardia in cardiac sarcoidosis. [PDF]
A 73-year-old man with history of pulmonary sarcoidosis was found to have runs of non-sustained bidirectional ventricular tachycardia (BVT) with two different QRS morphologies on a Holter monitor.

Connexin43 Deficiency Leads to Ventricular Arrhythmias by Reprogramming Proline Metabolism
The study demonstrated that connexin43 (Cx43) knockout caused arrhythmic phenotype and decreased proline content in vitro and in vivo. Mechanistically, Cx43 interacts with the amino acid transporter SNAT2 (sodium‐dependent neutral amino acid transporter), and its deficiency disrupts proline transport and metabolism.
