P-wave duration changes and dispersion in preeclampsia

European Journal of Obstetrics & Gynecology and Reproductive Biology, 2014
The purpose of this research was to study P wave parameters to determine the association between preeclampsia and future cardiovascular risk and to study the possible correlation between P waves and severity of preeclampsia.In this case-control study 58 pregnant women with preeclampsia and 30 normal pregnant women were compared by measuring maximum and

Effect of Birth Asphyxia on P Wave Dispersion

The Indian Journal of Pediatrics, 2013
To evaluate the cardiac conduction system using P wave dispersion on electrocardiogram and its relationship with the short term mortality and development of arrhythmia in asphyxiated neonates.Thirty term babies with evidence of asphyxia and without any congenital abnormalities were consecutively evaluated as cases.

P wave duration and dispersion in multiple sclerosis

Clinical Autonomic Research, 2005
Multiple sclerosis (MS) has been reported to be associated with extensive autonomic dysfunction as well as to involve the cardiovascular system. In this study we compared P wave duration and dispersion (PWD) of MS patients to healthy control subjects.Thirty-one MS patients (mean age 35 +/- 9 years) and 33 healthy control subjects (mean age 34+/-7 years)

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.

AB0862 Qt Dispersion and P Wave Dispersion in Fibromyalgia

Annals of the Rheumatic Diseases, 2014
Background Fibromyalgia syndrome is a chronic disease with unknown etiology, characterized by widespread pain. QT dispersion represents a general repolarization abnormality and autonomic dysfunction. Longer QT dispersion is associated with higher risk of ventricular arrhythmias, cardiac events and mortality.

P-wave dispersion in patients with Guillain–Barré syndrome

Acta Neurologica Belgica, 2016
Cardiac autonomic dysfunction assessed by the presence of arrhythmia, by the methods, such as heart rate variability or blood pressure variability, and by the electrocardiographic abnormalities is common in Guillain-Barré syndrome (GBS). The goal of present study was to analyze the P-wave dispersion (PWD), which is the non-invasive marker of atrial ...

Dispersion Measurements of P Waves and their Implications for Mantle Q p

Pure and Applied Geophysics, 2003
We analyze the anelasticity of the earth using group delays of P-body waves of deep (>200 km) events in the period range 4–32 s for epicentral distances of 5–85 degrees. We show that Time Frequency Analysis (TFA), which is usually applied to very dispersive surface waves, can be applied to the much less dispersive P-body waves to measure frequency ...

P-wave dispersion in familial dysautonomia.

The Israel Medical Association journal : IMAJ, 2011
Familial dysautonomia is a hereditary disease characterized by dysfunction of the sensory and autonomic nervous systems. Studies in patients with familial dysautonomia have shown that abnormal cardiac autonomic denervation might influence repolarization.
