The initiation of the P wave in an electrocardiogram is caused by atrial depolarization, which is the electrical activation of the atria as they contract to push blood into the ventricles. This electrical activity is generated by the sinoatrial (SA) node, the heart's natural pacemaker.

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.
What is the first wave of an ECG?
The first wave of an ECG is the P wave, which represents atrial depolarization as the electrical impulse spreads through the atria. It is the initial wave seen in a normal heart rhythm.
Which is faster an s-wave or a p-wave?
P-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.
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.
Which body wave is a longitudinal wave?
The primary body wave that is a longitudinal wave is the P-wave (primary wave). It is the fastest seismic wave and travels through the Earth's interior by compressing and expanding the rock in the direction of the wave's 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.
What type of waves are there?
p-wave s-wave l-wave
What is the fastest type of siesmic wave?
Primary Wave (P wave)
