What is the duration of a P wave?
The P wave refers to the electrocardiographic representation of electrical activation of the atrial myocardium. It can be measured using an electrocardiogram.
How do rock particles move during the passage of a P wave through rock?
A P wave is a type of seismic wave that is caused by an earthquake. P waves are the first seismic waves felt during an earthquake. When the P wave moves, rock particles move back and forth along the direction of the P wave.
Which wave travels farther p-waves or s-waves?
The velocity of s-wave is 60% of p-wave, for a given homogeneous and isotropic medium and a fixed time p-wave would travel farther.
What wave is recorded first on a seismograph?
Movement in the earth's crust, as in earthquakes.
What is S-P lag time?
the difference between the arrival of the p-wave and s-wave
On an electrocardiogram tracing atrial activity is represented by the?
p wave
What is the P wave of electrocardiogram closely followed by?
Contraction of both atria
What is required for the interpretation of the electrocardiogram?
Special training is required for interpretation of the electrocardiogram. To summarize in the simplest manner the features used in interpretations, the P wave of the electrocardiogram is associated with the contraction of the atria
What is the duration of a P wave?
The P wave refers to the electrocardiographic representation of electrical activation of the atrial myocardium. It can be measured using an electrocardiogram.
Does the first heart sound occurs at the same time as the P wave of the electrocardiogram?
yes
What generates the p wave of an electrocardiogram?
A P wave denotes atrial depolarization or when your atriacontracts. It is generated by the Sinoatrial (SA) node which is the primary pacemaker and signifies a Sinus Rhythm.
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.
What are pea waves?
A "p" wave is a particular point on an electrocardiogram tracing. It represents the contraction of the right and left atria. The electrocardiogram tracing is a tool that the physician uses to evaluate the health of the heart.
What would you see on the Electrocardiogram if the SA node did not fire?
An electrocardiogram would show reduced heart rate as other parts of the heart cause potentials at low rates. Also there would be no P wave.
What does a P wave record on an EKG?
The P wave represents atrial depolarization (they contract). In a normal EKG, the P-wave precedes the QRS complex. It looks like a small bump upwards from the baseline.
What does the P wave indicate?
The P wave indicates the depolarization (contraction) of the atria.Source: Chon, Elizabeth Gross, and Gilroy-Doohan, Mary,Flip and See ECG, W.B. Saunders Company
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.
