Effect of ECG filtering on time domain analysis of the P-wave

, 2008
The aim of this study was to assess the effect of filtering techniques on the time-domain analysis of the P-wave. Multi-lead ECG recordings obtained from chronic AF patients after successful external cardioversion have been acquired.

Assessment of P wave duration and P wave dispersion in high level football referees

, 2016
BACKGROUND: P wave dispersion and P wave maximal duration reflect the activation of atrial muscle and is influenced by the mass of the excited tissue. It may reflect atrial remodelling, most likely atrial fibrosis.

Controlling Grain Growth in Powder Bed Fusion of Yttria‐Stabilized Zirconia Using Femtosecond Lasers: Challenges and Methodological Insights

Advanced Engineering Materials, EarlyView.
Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

The Role of P‐Wave Variables in Enhancing Prediction of New‐Onset Atrial Fibrillation in Patients With Acute Myocardial Infarction

Annals of Noninvasive Electrocardiology
Background After acute myocardial infarction (AMI), it is common to observe new‐onset atrial fibrillation (NOAF), which is often related to a negative prognosis. Some P‐wave variables (P‐wave duration [PWD], P‐wave amplitude, and interatrial block [IAB]),
