During this time, surface ECG recordings show the P-wave. If the atrial depolarization pattern deviates from the physiological pattern, the morphology of the P-wave changes, resulting in prolonged and highly variable P-waves. Since abnormal P-waves have been observed in patients prone to AF, a...
How and why does the size of the P wave differ from the size of the QRS complex? which electrical event produces QRS wave? What is the condition is indicated by long P-R interval? Give the meaning for the following abbreviation: PMS ...
Although often ignored, assessment of the electrical axis is an integral part of ECG interpretation. The electrical axis reflects the average direction of ventricular depolarization during ventricular contraction. The direction of the depolarization (and thus the electrical axis) is generally alongside the...

Presents an automatic analysis method of the P-wave, based on lead II of a 12 lead standard ECG, which will be applied to the detection of patients prone to atrial fibrillation (AF), one of the most frequent arrhythmias. It focuses first on the segmentation of the electrocardiogram P-wave...
Analysis of ECG P-wave parameters before ablation The preoperative P-wave parameters (indicates as pre-) of all patients were analyzed and compared (Table 2). Significant differences were observed between the non-recurrence group and the recurrence group in pre-Pmax (124.21 ± 12.03 vs....
Reliable P wave detection is necessary for accurate and automatic electrocardiogram (ECG) analysis. Currently, methods for P wave detection in physiological conditions are well-described and efficient. However, methods for P wave detection during patholo
The P wave in an ECG is a recording of the depolarization of the right atrium and left atrium. Depolarization refers to when the muscles of these...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
Detection of patients at risk for recurrence of atrial fibrillation after successful electrical cardioversion by signal-averaged P-wave ECG The aim of the study was to assess the value of signal-averaged ECG of P-wave in predicting recurrence of atrial fibrillation after direct-current electric......
Finally we described the utility of a careful evaluation of P wave duration and dispersion measured on standard ECG and signal-averaged ECG (SAECG) recordings as potential atrial fibrillation predictors and markers of history of paroxysmal atrial fibrillation....
