P‐Wave Duration in Lead aVR and the Risk of Atrial Fibrillation in Hypertension

Abstract

Simple measurement of PW duration in lead aVR allows effective identification of AF patients in a population of hypertensives. Confirmation of this finding in a larger population would provide a simple and effective risk marker of AF in hypertensive patients.

Obesity and atrial fibrillation: A comprehensive review of the pathophysiological mechanisms and links

“…Chá vez et al investigated the relationship between blood pressure, LV mass index, and P-wave dispersion in a pediatric population and reported increased P-wave dispersion in pre-and hypertensive children, and a dependence of the P-wave dispersion on the LV mass index [41]. In the same line, Francia et al reported that a simple measurement of P-wave duration in lead aVR allows effective identification of AF risk in a population of hypertensive patients [42].…”

Atrial electrocardiography in obesity and hypertension: Clinical insights from the Polish‐Norwegian Study (PONS)

“…Prolongations of the PR interval and of several P‐wave indices derived from the 12‐lead resting electrocardiogram (ECG) have been proposed as intermediate phenotypes to mark this atrial remodeling process . Several studies have found that these ECG measures are associated with an increased risk of new‐onset AF and are also independently associated with obesity , metabolic syndrome , and HTN status . As obesity and HTN have a high prevalence and often coexist, we hypothesized that their single and joint effects on atrial remodeling would be reflected in the PR interval and P‐wave durations.…”

Electrocardiographic P‐Wave Duration, QT Interval, T Peak to End Interval and Tp‐e/QT Ratio in Pregnancy with Respect to Trimesters

“…Elevated atrial pressure due to card‐iac and noncardiac conditions, ischemia and metab‐olic stress cause atrial remodeling thus provide a substrate for atrial fibrillation . Hypertension, diastolic dysfunction, diabetes, advanced age, and increased BMI were found to be associated with prolongation of P‐wave indices due to atrial remodeling …”
