Esophageal Electrical Cardioversion of Atrial Fibrillation: When Esophagus Gives a Help to Cardiologists

Cardiology Research and Practice, 2011
Atrial fibrillation is a common clinical disease especially in the elderly and in patients with organic heart disease. Electrical cardioversion is the first choice therapeutic approach for patients in which sinus rhythm could improve the quality of life

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Optimised Internet of Thing framework based hybrid meta‐heuristic algorithms for E‐healthcare monitoring

IET Networks, EarlyView., 2022
Abstract Everything can be connected in the Internet of Things (IoTs) technology that enables efficient communication between connected objects. IoTs industry‐based meta‐heuristic and mining algorithms, which are considered an important field of Artificial Intelligence will be used to construct a healthcare application in this study for lowering costs,

The Deubiquitinase UCHL1 Drives Susceptibility to Atrial Fibrillation by Stabilizing CaMKII‐δ

Advanced Science, EarlyView.
UCHL1 is highly upregulated in mice and patients with AF. UCHL1 directly binds to and removes K48‐linked polyubiquitin chains from CaMKII‐δ at K251 and enhances CaMKII‐δ stability, which activates RyR2, disrupts Ca2+ handling, and promotes AF. These findings establish UCHL1 as a critical regulator of CaMKII‐δ stability and AF‐related Ca2+ handling ...

Using and interpreting cost-effectiveness acceptability curves: an example using data from a trial of management strategies for atrial fibrillation [PDF]

, 2006
Background: The cost-effectiveness acceptability curve (CEAC) is a method for summarizing the uncertainty in estimates of cost-effectiveness. The CEAC, derived from the joint distribution of costs and effects, illustrates the (Bayesian) probability ...

1,2‐propanediol reformulation improves tribromoethanol safety and reveals pontine GABRA1 enrichment as a candidate mechanistic correlate of anesthesia

Animal Models and Experimental Medicine, EarlyView.
This study develops a reformulated tribromoethanol (TBE) anesthetic using 1,2‐propanediol as a solvent to overcome solvent‐related toxicity. The novel formulation demonstrates, cardiovascular stability, and survival in prolonged protocols. It provides potent, dose‐dependent anesthesia without strain or sex differences.

Chronic beta-adrenoceptor blockade and human atrial cell electrophysiology: evidence of pharmacological remodelling [PDF]

, 2003
<b>Objective:</b> Chronic beta-adrenoceptor antagonist (β-blocker) treatment reduces the incidence of reversion to AF in patients, possibly via an adaptive myocardial response.

Cardiac morphological and morphometric analysis of Ardea alba

The Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Coronary Perforation During Excimer Laser Angioplasty in a Patient With Prior Thoracic Radiotherapy

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of heavily calcified coronary lesions remains challenging despite advances in plaque‐modifying technologies. Excimer laser coronary angioplasty (ELCA) is an effective adjunctive strategy with a low risk of no‐reflow. Case Summary A 75‐year‐old woman with non–ST‐segment elevation acute coronary syndrome and severe left ...
