Causal relationships between eruptive prominences and coronal mass ejections [PDF]

open access: yesAnnales Geophysicae, 2008
A close association between eruptive prominences and CMEs, both slow and fast CMEs, was reported in many studies. Sometimes it was possible to follow the material motion starting from the prominence (filament) activation to the CME in the high corona.

Accurate Hugoniots and sound velocities of bismuth under shock compression in the 38-100 GPa range

open access: yesAIP Advances, 2018
Dynamic compression experiments of bismuth (Bi) in a shock pressure range of 38-100 GPa were conducted using an explosive drive. The time-resolved particle velocity profiles at the Bi/LiF (lithium fluoride) interface and the impact velocities were ...

The effect of recanalization of a chronic total coronary occlusion on P-wave dispersion [PDF]

open access: yesJournal of Cardiovascular and Thoracic Research, 2021
Introduction: P-wave dispersion (PWD) obtained from the standard 12-lead electrocardiography (ECG) is considered to reflect the homogeneity of the atrial electrical activity.

Simulated Obstructive Sleep Apnea Increases P-Wave Duration and P-Wave Dispersion. [PDF]

open access: yesPLoS ONE, 2016
BACKGROUND:A high P-wave duration and dispersion (Pd) have been reported to be a prognostic factor for the occurrence of paroxysmal atrial fibrillation (PAF), a condition linked to obstructive sleep apnea (OSA).

The P wave dispersion—one pixel, one millisecond

open access: yesReviews in Cardiovascular Medicine, 2021
The electrophysiological activity of the heart is recorded and presented in form of electrocardiogram (ECG). In 1998 the concept of P wave dispersion as the risk factor for atrial fibrillation (AF) recurrence was introduced.

P wave dispersion and maximum P wave duration are independently associated with rapid renal function decline. [PDF]

open access: yesPLoS ONE, 2012
The P wave parameters measured by 12-lead electrocardiogram (ECG) are commonly used as noninvasive tools to assess for left atrial enlargement. There are limited studies to evaluate whether P wave parameters are independently associated with decline in ...

P Wave Indices—Advancing Our Understanding of Atrial Fibrillation-Related Cardiovascular Outcomes

open access: yesFrontiers in Cardiovascular Medicine, 2019
Atrial fibrillation (AF) is associated with an increased risk of ischemic stroke, heart failure, cognitive decline, dementia, myocardial infarction, sudden cardiac death (SCD), and all-cause death.
