Effects of Coupling Between Wave‐Induced Fluid Flow and Elastic Scattering on P‐Wave Dispersion and Attenuation in Rocks With Aligned Fractures

Journal of Geophysical Research: Solid Earth, 2020
Fracture‐background wave‐induced fluid flow (FB‐WIFF) and elastic scattering are considered two important mechanisms for P‐wave dispersion and attenuation in the fractured and porous fluid‐saturated rock.

P wave dispersion – fading light of a popular parameter

, 2020
The P wave dispersion concept was created to describe the non-uniform atrial conduction as a separate AF factor. However the major assumptions of the theory are inconsistent with the main principle of electrocardiography, which assumes that 12 ...

P-Wave Dispersion in Panic Disorder

Psychosomatic Medicine, 2007
P-wave dispersion (PWD) is defined as the difference between the maximum and the minimum P-wave (Pmax and Pmin, respectively) duration. Significant variation in cardiac atrial PWD has been correlated with changes in systemic autonomic tone such as during periods of anxiety. It is also known that the degree of PWD seen on 12-lead electrocardiogram (ECG)

P wave dispersion and silent atrial fibrillation in cryptogenic stroke: the pathogenic role of inflammation.

Cardiovascular & Haematological Disorders - Drug Targets, 2019
BACKGROUND Cryptogenic stroke (CS) represents 25% of ischemic strokes. Especially after CS, the detection of atrial fibrillation (AF) is important because it provides clues to the mechanism of stroke.

Evaluation of atrial electromechanical functions in dipper and nondipper hypertension patients using left atrial strain P‐wave dispersion and P terminal force

Echocardiography, 2018
Nondippers are known to carry a high risk of cardiovascular morbidity and mortality. The aim of this study was to investigate the effects of dipper and nondipper status of hypertension on left atrial (LA) systolic and diastolic functions using two ...

P wave dispersion in patients with hypochondriasis

Neuroscience Letters, 2010
P wave dispersion (Pd), defined as the difference between the maximum and the minimum P wave duration, has been associated with anxiety. Thus, we wondered whether Pd in hypochondriasis which is associated with anxiety differed from that in healthy controls.

P wave dispersion in familial Mediterranean fever

Rheumatology International, 2010
Familial Mediterranean fever (FMF) is a hereditary disease characterized by recurrent and self-terminated attacks of fever and polyserositis. A recent study found that FMF patients had an abnormally high P wave duration and P wave dispersion, markers for supraventricular arrhythmogenicity.
