Is there a utility for QRS dispersion in clinical practice? [PDF]
Prognostic markers derived from standard ECG have always been seductive. Increased dispersion of durations of the P wave, of the QRS complex, or of the QT interval has been associated with the risk of atrial fibrillation, ventricular arrhythmias, sudden ...

Fast Time-Evolution of Matrix-Product States using the QR decomposition [PDF]
We propose and benchmark a modified time evolution block decimation (TEBD) algorithm that uses a truncation scheme based on the QR decomposition instead of the singular value decomposition (SVD). The modification reduces the scaling with the dimension of the physical Hilbert space $d$ from $d^3$ down to $d^2$. Moreover, the QR decomposition has a lower

Predicting arrhythmias in primary prevention heart failure patients: picking up the fragments [PDF]
Identifying patients with high-risk heart failure (HF) who would benefit from an implantable cardioverter-defibrillator (ICD) remains controversial. A potential marker for arrhythmic sudden death is fragmented QRS (fQRS).

Effects of capillary number and flow rates on the hydrodynamics of droplet generation in T-junction microfluidic systems [PDF]
The hydrodynamics of droplets is significant in wide-ranging applications involving immiscible fluids and emulsions in food and pharmaceutical. The control and manipulation of droplets are primarily a function of flow governing and geometrical parameters.

Electrocardiogram of Clinically Healthy Mithun (Bos frontalis): Variation among Strains [PDF]
A study was conducted to establish the normal electrocardiogram in four different genetic strains of mithun (Bos frontalis). Electrocardiography, cardiac electrical axis, heart rate, rectal temperature and respiration rate were recorded in a total of 32 ...

Myotonic dystrophy type 1: A comparison between the adult‐ and late‐onset subtype
Abstract Introduction/Aims Although the extent of muscle weakness and organ complications has not been well studied in patients with late‐onset myotonic dystrophy type 1 (DM1), adult‐onset DM1 is associated with severe muscle involvement and possible life‐threatening cardiac and respiratory complications.

Postextrasystolic Changes in the Complexity of the QRS Complex and T Wave [PDF]
We tested the hypothesis that ventricular repolarization of the first sinus beat following a ventricular premature beat (VPB) can be modulated in the absence of clearly discernible T‐wave changes. We applied principal component analysis (PCA) to assess QRS and T‐wave complexity of sinus beats preceding and following VPBs in multiple 10‐second resting ...

Detection of electrocardiogram QRS complex based on modified adaptive threshold [PDF]
It is essential for medical diagnoses to analyze Electrocardiogram (ECG signal). The core of this analysis is to detect the QRS complex. A modified approach is suggested in this work for QRS detection of ECG signals using existing database of arrhythmias.

A Multi-Lead Fusion Method for the Accurate Delineation of QRS Complex Location in 12 Lead ECG Signal [PDF]
This paper presents a multi-lead fusion method for the accurate and automated detection of the QRS complex location in 12 lead ECG (Electrocardiogram) signals. The proposed multi-lead fusion method accurately delineates the QRS complex by the fusion of detected QRS complexes of the individual 12 leads.
