Cardiac heterogeneity in patients with chronic urticaria; A perusal of P wave and QT dispersions

Medicine Science, 2022
Data on how the heart is affected in Chronic Urticaria (CU), a common annoying chronic dermatological disease, is quite limited. The electrocardiographic parameters; P wave dispersion (PWD) and QT dispersion (QTD) have been consistently reported to be ...

Effects of haemodialysis on maximum P wave duration and P wave dispersion [PDF]

Nephrology Dialysis Transplantation, 2002
Analysing a 12-lead surface electrocardiogram (ECG), the inter-lead variability of the P wave interval, i.e. P wave dispersion, is defined as the difference between the maximum and the minimum P wave duration. Our aim was to assess the effect of haemodialysis on P wave duration and dispersion in non-diabetic patients with end-stage renal failure on ...

P Wave Dispersion in COVID-19

Eastern Journal Of Medicine, 2022
The effects of COVID-19 on the heart are still not fully known. In this study, we investigated how COVID-19 affects the P interval. Electrocardiographies (ECG) of 30 COVID-19 patients and the control group consisting of 23 healthy volunteers were examined and dispersion (Pd) of the P wave was calculated.

P‐Wave dispersion increases in prehypertension

Blood Pressure, 2009
Prolongation of P-wave durations and increased P-wave dispersion are independent predictors of atrial fibrillation (AF). AF is the most common arrhythmia of the general population. Prehypertension, including those with systolic blood pressure ranging from 120-139 mmHg or diastolic blood pressure ranging from 80-89 mmHg was described by JNC7 ...

P‐wave duration and P‐wave dispersion in patients with dilated cardiomyopathy [PDF]

European Journal of Heart Failure, 2004
AbstractBackground:P‐wave dispersion (PWD) has been reported to be associated with inhomogeneous and discontinuous propagation of sinus impulses. In the present study, we aimed to investigate PWD in patients with dilated cardiomyopathy.Method:The study population consisted of 72 patients with dilated cardiomyopathy and 72 healthy control subjects.

QTC Dispersion and P-Wave Dispersion during Migraine Attacks

Cephalalgia, 2006
The aim of this study was to investigate increase of QTc dispersion and P-wave dispersion during migraine attacks. Fifty-five patients (16–65 years of age, 49 women, six men) with migraine were included in our study. Heart rate, QTc interval, maximum and minimum QTc interval, QTc dispersion, maximum and minimum P-wave duration and P-wave dispersion ...

P wave peak time and P wave dispersion in severe COVID-19 infection.

European review for medical and pharmacological sciences, 2022
With this study, we aimed at evaluating the association between electrocardiographic P wave indices and the severity of COVID-19 infection indicated as intensive care unit (ICU) admission.We included 247 patients who were hospitalized with a diagnosis of COVID-19 infection and underwent 12 lead standard Electrocardiography (ECG). P wave indices, P wave

P wave dispersion and maximum P wave duration are associated with renal outcomes in chronic kidney disease. [PDF]

PLoS ONE, 2014
P wave parameters measured by 12-lead electrocardiogram (ECG) are commonly used as a noninvasive tool to evaluate left atrial enlargement. This study was designed to assess whether P wave parameters were associated with renal outcomes in chronic kidney ...
