The P wave on an electrocardiogram (ECG) represents atrial depolarization, which is the electrical activity that triggers the contraction of the atria. It occurs when the sinoatrial (SA) node generates an electrical impulse that spreads through the atria, causing them to contract and push blood into the ventricles. The P wave is typically the first deflection seen on the ECG, preceding the QRS complex.
What else can I help you with?
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 next type of seismic wave to arrive after the P-wave is the S-wave.
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?
I believe it is the P Wave. A good way to remember is all of the Waves are in alphabetical order. P Wave, Q-R-S Waves and the T Wave
What is the ECG wave that results from the depolarization of the ventricle?
the P wave
What contraction of the atria results from which wave of depolarization on the ECG tracing?
P wave
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 next type of seismic wave to arrive after the P-wave is the S-wave.
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
The p in an electrocardiogram sHow is what?
The P wave is the first wave in an ECG complex, and it results from the atria depolarizing. It may not be present in arrhythmias where the atria do not necessarily depolarize, such as junctional or ventricular escape rhythms, and at times when the atria are depolarizing abnormally this will be reflected in the P wave's replacement by abnormal waves, such as the low-amplitude "squiggle" seen in atrial fibrillation, or the "sawtooth" pattern seen in atrial flutter.
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.
