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 ...

Charge Directed Selective Co‐Assembly of Ionic Complementary Peptide Binary Mixtures

Small, EarlyView.
Multi‐component peptide systems enable the development of multi‐functional and tunable materials, yet, controlling the co‐assembly of such complex systems remains challenging. This study demonstrates that rational design of peptide charge distribution, together with controlling parameters (pH, stoichiometry, and concentration), can guide selective co ...

Analysis of Abnormal Intra-QRS Potentials in Signal-Averaged Electrocardiograms Using a Radial Basis Function Neural Network

Sensors, 2016
Abnormal intra-QRS potentials (AIQPs) are commonly observed in patients at high risk for ventricular tachycardia. We present a method for approximating a measured QRS complex using a non-linear neural network with all radial basis functions having the ...

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.
