A wave of depolarization occurs when there is a sudden influx of positive ions, typically sodium ions, into the neuron, leading to a reversal of the cell's membrane potential. This helps in transmitting electrical signals along the neuron through a process known as action potential propagation.
What else can I help you with?
As a wave of electrical depolarization moves parallel to the direction of a lead if it moves towards the positive pole of the lead a?
positive deflection is recorded on the ECG, while if it moves towards the negative pole, a negative deflection is recorded.
What happens when a wire moves up and down repeatedly?
When a wire moves up and down repeatedly, it generates an electromagnetic wave. This wave carries energy along the wire and through the surrounding space. The frequency at which the wire moves up and down will determine the frequency of the electromagnetic wave produced.
What wave comes after the t wave of an ECG?
The next wave after the T wave in an ECG is the P wave, which represents atrial depolarization.
Is a hand wave transverse or longitudnal?
A hand wave is a transverse wave because the motion of the wave is perpendicular to the direction in which the wave travels. In a hand wave, the hand moves up and down while the wave moves horizontally.
A wave in witch matter moves back and forth in the direction of the wave?
This describes a mechanical wave, where matter oscillates in the same direction as the wave propagation. An example of this is a water wave as the water moves up and down in the direction of the wave.
What is the electrical signal that typically moves from the cell body down the axon to the axon terminals?
The electrical signal that moves from the cell body down the axon to the axon terminals is called an action potential. This signal is generated when a neuron reaches a specific threshold, causing a rapid depolarization of the membrane due to the influx of sodium ions, followed by repolarization as potassium ions exit the cell. This wave of depolarization travels along the axon, ultimately leading to the release of neurotransmitters at the axon terminals.
The portion of the ECG that corresponds to atrial depolarization is the?
The portion of the ECG that corresponds to atrial depolarization is called the P wave. The P wave is the first wave on the ECG.
Is depolarization the resting state of the p wave?
No, depolarization is not the resting state of the P wave. Depolarization is the process where the heart muscle contracts in response to an electrical signal. The P wave represents atrial depolarization, the electrical activity that triggers the contraction of the atria in the heart.
What is the ECG wave that results from the depolarization of the ventricle?
the P wave
The p wave of the electrocardiogram is a signal from?
The P wave on ECG corresponds to electrical depolarization of the atria. It should be positive in lead II and negative in aVR when the P wave originates in the sinoatrial node.
As a wave of electrical depolarization moves parallel to the direction of a lead if it moves towards the positive pole of the lead a?
positive deflection is recorded on the ECG, while if it moves towards the negative pole, a negative deflection is recorded.
Does the p wave in an ekg indicate atrial depolarization?
No it does not. Atrial repolarization is generally not visible on the telemetry strip because it happens at the same time as ventricular depolarization (QRS complex). The P wave represents atrial DEpolarization (and atrial systole). Atrial repolarization happens during atrial diastole (and ventricular systole).
What contraction of the atria results from which wave of depolarization on the ECG tracing?
P wave
What part of an ecg do atria contract?
Atrial depolarization occurs at the P wave. The atrial contraction occurs at the peak of the wave at the influx of calcium ions to prolong depolarization.
What wave form does Right and left atrial depolarization produce?
Right and left atrial depolarization produce a P wave on an electrocardiogram (ECG) waveform. This represents the depolarization of the atria as they contract to push blood into the ventricles.
What happens when a wire moves up and down repeatedly?
When a wire moves up and down repeatedly, it generates an electromagnetic wave. This wave carries energy along the wire and through the surrounding space. The frequency at which the wire moves up and down will determine the frequency of the electromagnetic wave produced.
What wave comes after the t wave of an ECG?
The next wave after the T wave in an ECG is the P wave, which represents atrial depolarization.
