Jervell and Lange‐Nielsen Syndrome Related Clinical Genetics and Experimental Models

Pediatric Discovery, EarlyView.
ABSTRACT Jervell and Lange‐Nielsen syndrome (JLNS) is defined by electrocardiographic QT prolongation and sensorineural hearing loss, caused by homozygous or compound heterozygous variants in KCNQ1 and/or KCNE1. KCNQ1 encodes the alpha subunit Kv7.1 of the ion channels accountable for slow delayed rectifier potassium currents (IKs), whereas KCNE1 ...

Cardiac resynchronization therapy and pulmonary artery banding in advanced heart failure infants with left ventricular dilated cardiomyopathy and left bundle branch block

Pediatric Investigation, EarlyView.
The combination of cardiac resynchronization therapy and pulmonary artery banding was associated with substantial improvement in advanced heart failure infants with left ventricular dilated cardiomyopathy and left bundle branch block. Most patients exhibited marked improvement in clinical status and ventricular function, along with a reduction in QRS ...

Role of novel automated methods in pulse signal analysis to screen for sleep‐disordered breathing among patients on chronotropic medications

Sleep Research, EarlyView.
Abstract Study objectives To investigate the use of automated analysis to detect heart rate accelerations (HRAs) to screen for sleep‐disordered breathing (SDB) among patients who use chronotropic medications. Methods Nocturnal polysomnography (NPSG) recordings from 933 participants in the Sleep Heart Health Study were analyzed using an automated method

How to facilitate ultrasound examination of the fetal heart: the 5‐4‐3‐2‐1 method

Ultrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT We propose a new standardized, systematic method of fetal cardiac screening, the step‐by‐step ‘5‐4‐3‐2‐1’ method. This method is based on understanding the cardiac structures through a process of navigating between the different recommended views during an abdominothoracic sweep, following a user‐friendly checklist to identify the main ...

Effects of Endocardial Microwave Energy Ablation [PDF]

, 2005
Until recently the treatment of atrial fibrillation (AF) consisted primarily of palliation, mostly in the form of pharmacological intervention. However because of recent advances in nonpharmacologic therapies, the current expectation of patients and ...

ECG‐TransCovNet: A hybrid transformer model for accurate arrhythmia detection using Electrocardiogram signals

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Abnormalities in the heart's rhythm, known as arrhythmias, pose a significant threat to global health, often leading to severe cardiac conditions and sudden cardiac deaths. Therefore, early and accurate detection of arrhythmias is crucial for timely intervention and potentially life‐saving treatment.
