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...
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...
One of the main points of interest in the study of the dynamic behaviour of ECG time intervals is the accuracy with which characteristic moments can be estimated in the various waveform segments such as the P wave or QRS complex. In this study, the error involved in such estimation is regar...
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
