To evaluate the P wave changes in the electrocardiogram (ECG) in chronic lung diseases, we examined ECGs from twenty patients with interstitial pulmonary fibrosis (the FLD group) and twenty patients with chronic obstructive lung disease (fifteen with pulmonary emphysema and five with bronchial asthma...
Here, we hypothesized that existing differences in P-wave morphology on electrocardiograms (ECG) may be associated with atrial conduction changes. Seventy-one children with a CN were recruited and matched to 60 healthy controls. P-wave duration, P-wave amplitude, P dispersion (Pd), QRS, PR, ...
Because the ST segment and the T-wave are electrophysiologically related, changes in the ST segment are frequently accompanied by T-wave changes. The term ST-T segment changes (or simply ST-T changes) is used to refer to such ECG changes. ...
P-wave changes as an index of hypertensive organ damage and a predictor of cardiovascular events: can the P wave be used to assess atrial reverse remodeling?. Hypertens Res 45, 1400–1403 (2022). https://doi.org/10.1038/s41440-022-00947-8 Download citation Received08 April 2022 Revised16 ...
Objective To explore the relationship between P - wave dispersion ( Pwd ) of surface electrocardiogram ( ECG ) and atrial arrhythmia ( AR ). 目的探讨体表心电图P波离散度 ( Pwd ) 与房性心律失常 ( AR ) 的关系. 互联网 Conclusion ECG P wave amplitude changes are a useful standard in evalua...
Related to P-wave:S-wave,seismic (pē′wāv′) n. A seismic wave that travels very quickly through the earth, causing the rocks it passes through to change in volume and their particles to vibrate parallel to the direction of wave propagation. P-waves can travel through solids, liquids, ...

In our study, we compared P wave changes in patients who were and were not found to have catheter related atrial fibrillation during EPS. Material and Methods: One hundred forty five patients who had normal EPS findings and who were found to have catheter related atrial fibrillation were ...
P-wave parameters derived from ECG have demonstrated associations with AF recurrence. [9, 10] In this study, the predictive significance of P-wave parameters and their changes in predicting PAF recurrence in patients following catheter ablation was analyzed. A nomogram predictive model was developed ...
This study compares the changes in P-wave parameters between both ablation methods. Methods This single-centre retrospective study included contact force RF and second-generation cryo for PAF between 2018 and 2019. Procedure success was defined by freedom of ECG-documented AF at 12 months. Digital...
