The electrical milestone event that occurs at the P wave of the cardiac cycle of the EKG is atrial depolarization. The upward stroke is right atrial depolarization, and the downward stroke is left atrial depolarization. Normally, this lasts for no more than 0.11 sec.
The P wave represents atrial depolarization in an ECG, so it occurs just before the P wave on the ECG tracing. It signifies the activation of the atria as they prepare to contract and pump blood into the ventricles.
Immediately after the P wave occurs the P-R Segment, which is the time taken by an impulse to travel from the SA node to the Ventricles. Then the QRS complex occurs.

Is surface wave faster then a p wave?
no a p wave is faster than s wave
Which type of body wave always arrives after the P-wave?
The S-wave, or secondary wave, always arrives after the P-wave. S-waves are slower than P-waves and are the second wave to arrive during an earthquake.
What is a p wave?
A P wave is a type of seismic wave generated by an earthquake that travels the fastest through the Earth's layers. It is the first wave to arrive at a seismograph station and is known as a compressional wave because it pushes and pulls the rock particles as it moves.
What directions do the particles of a p wave move?
P-wave particles move in the same direction as the wave's propagation, which is the direction of energy transfer. This movement is back and forth in the direction of the wave.
When finding an epicenter do you subtract s wave minus the p wave?
No, to find the epicenter of an earthquake, you use the difference in arrival times between the P-wave and the S-wave at a seismograph station. The greater the time difference between the two waves, the farther the earthquake's epicenter is from that particular station. Subtraction is not directly involved in this process.
What happens in the cardiac cycle immediately before P wave?
Immediately before the P wave in the cardiac cycle, the atria contract (atrial systole), pushing blood into the ventricles. This phase is called atrial depolarization. The P wave represents the depolarization of the atria on an electrocardiogram (ECG).
Which is faster an s-wave or a p-wave?
P-Wave
What does the s stand for in s waves?
S-wave stands for : Secondary wave. It comes after the P-wave and goes before the L-wave.
Is surface wave faster then a p wave?
no a p wave is faster than s wave
Which type of body wave always arrives after the P-wave?
The S-wave, or secondary wave, always arrives after the P-wave. S-waves are slower than P-waves and are the second wave to arrive during an earthquake.
Which wave the p-wave or s-wave would arrive at seismometer afer the eatrhquake?
Both, first the P wave Then the S wave.
The first s-wave arrive at a seismograph station 11 minutes after an earthquake occurred how long after the arrival of the first p-wave did the first s-wave arrive?
The P-wave generally arrives before the S-wave during an earthquake. The time difference between them can help determine the distance to the earthquake's epicenter. In this case, if the S-wave arrived 11 minutes after the earthquake, you would need to calculate the time difference between the arrival of the P-wave and the S-wave to determine how long after the P-wave arrival the S-wave arrived.
What type of seismic wave that compresses and expands the ground?
Longitudinal Waves
Is a P-wave a seismic wave?
Yes. P-waves are known as primary waves and are a compressional or longitudinal wave.
What is the fasts wave?
They call it the Primary wave or a P-wave
Which body waves is a longitudinal wave?
The primary body wave that is a longitudinal wave is the P wave. P waves are compressional waves that travel through solid and liquid materials by causing particles to move in the same direction of wave propagation.
How do you find p wave arrival time?
To find the P-wave arrival time, you need to identify the initial sharp upward deflection on the seismogram. This indicates the arrival of the P-wave. Measure the time from the origin of the seismic event to the arrival of the P-wave to determine the P-wave arrival time.
