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...
By involving the rules into the decision process, we are able to find the P wave in the correct location or, alternatively, not to search for it at all. In contrast to another studies, we use three, highly variable annotated ECG databases, which contain both normal and pathological records...
However, the surface 12-lead ECG is a very helpful tool and the use of P-wave morphology (PWM) on surface ECG to localise the site of focal AT is of paramount importance. Subtle ECG changes with respect to PWM in AT could be mistaken as sinus rhythm (SR). We report a case of a ...

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....
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
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....
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 ...
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...
P-wave detection rate of 96.95% with false positive and false negative percentage of 2.62% and 3.01% has been reported. Similarly, T-wave detection rate of 98.01% with false positive and false negative percentage of 3.08% and 1.93% has been reported. 展开 关键词: ECG, P and T-wave ...
