Define P-wave. P-wave synonyms, P-wave pronunciation, P-wave translation, English dictionary definition of P-wave. n. A seismic wave that travels very quickly through the earth, causing the rocks it passes through to change in volume and their particles
The P wave, also the Primary wave, is the fastest wave. Due to its high speed, one can feel a jolt like the sensation when the wave arrives within close proximity to the human body. Question 2: What does an abnormal P wave indicate? Answer 2: P-wave abnormality in an ECG indicates...
Electrocardiogram (ECG): Definition & Wave Types from Chapter 6 / Lesson 5 244K An electrocardiogram (ECG) records the flow of electrical current on three distinct waves. Explore the purpose of an ECG, the three wave types, and the purpose of each wave on an ECG. Related...

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...

Ventricular extrasystoles P waveP wave detectionPathological ECG signalThis work introduces a new method for P wave detection in ECG signals during ventricular extrasystoles. The authors of previous works which deal with detection of P waves tested their algorithms......
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
To detect the P wave, you can search for the local maximum before the R peak. For the T wave, look for the local maximum after the R peak. Here is a simplified example of Matlab code to detect the P, Q, R, S, T points on an ECG waveform: ...
