What is the difference Between S waves P waves?
P-waves are faster than s-waves. Both can pass through solid rock, but only p-waves can pass through gases and liquids === ===
Do p waves s waves transverse waves or surface waves arrive first?
P waves arrive first.
After an earthquake which type of seismic wave arrives first at a seismometer?
P waves (APEX)
What is the abbreviation for primary waves?
P-waves
A seismograph can only measure P waves?
false. it can measure P waves, S waves and surface waves
What does a segment of an ECG tracing indicate?
P waves represent the atrial depolarization. QRS complex represent the ventricular depolarization. T waves represent the ventricular repolarization.
What is ventricular escape?
purkinjie fiber develops a rhythm of its own & ventricular contraction occur
How do you determine whether the atrial rhythm on an ecg tracing is regular or irregular?
If there is the same distance between each P wave it is regular. If the distances between the P waves varies it is irregular. Also, in a regular rhythm all the P waves should look the same.
What rhythm has 3 p waves for every qrs?
3p+ equals the amount of khars in a world
Is ventricular tachycardia a type of abnormal heart rhythm?
Ventricular tachycardia is an abnormal heart rhythm in which the heart beats rapidly due to electrical stimulation coming from the ventricle.
Where on the rhythm strip is the P wave located for junctional rhythm?
P waves occur from the sinoatrial node and indicate the atrial component of a heart rate. Junctional rhythms occur when the AV node (below the sinoatrial node) takes over. Therefore, in most junctional rhythms there are no p waves.
The QRS complex in an electrocardiogram results from?
An Electrocardiogram of a single heart beat shows three distinct waves. These are the P, QRS and T Waves. The QRS wave (normally the largest spike) in the electrocardiogram, is that of the ventricles depolarizing and contracting.
For which cardiac rhythm and other problems is CPR required?
The two most common heart rhythms that require CPR is ventricular tachycardia and ventricular fibrillation. Ventricular tachycardia is an extremely rapid cardiac rhythm and ventricular fibrillation is an abnormal cardiac rhythm. For an adult, if the person is unconscious and not breathing, CPR is required. There are numerous reasons an adult would be unconscious and not breathing; all require CPR.
Which heart rhythm often converts to ventricular fibrillation?
Ventricular Tachycardia
What is the most common rhythm following cardiac arrest?
ventricular fibrillation
What is the correct order of ECG waves?
P wave - represents atrial depolarization (contraction) QRS complex - ventricular depolarization T wave - ventricular repolarization (relaxation) atrial repolarization is "buried" within the QRS Complex
What is the term used to describe an irregularity in the hearts rhythm?
arrhythmia ventricular fibrillation
