What is the sequence of blood through the heart?
The wave of contraction in heart is initiated by S.A. Node which leads left auricles to contract. This wave of contraction is received by A.V.Node which contracts right auricle and spreads the wave of contraction to bundle of his and finally to purkinje fibre which contracts the two ventricles simultaneously anterioposteriorly. Therefore sequence of contraction is 1Left Auricle 2 Right auricle 3 ventricle
What are the 3 components of the ECG trace?
The EKG or ECG components are the P wave (contraction of the atria), the QRS complex (the contraction of the ventricles) and the T wave (repolarization of the ventricles).
What is the direction of a wave's motion called?
Well, it's often referred to as the direction of propagation of the wave.
The period during which the ventricles are depolarizing which precedes their contraction?
QRS wave
What is non q wave heart attack?
No. I had an MI confirmed by elevated enzymes they told me I had a non Q wave heart attack. what is the difference between a regular heart attack and a non q wave heart attack?
Why is the direction of the wave of contraction so important in the heart?
The direction of the wave of contraction in the heart is important because it decides where the blood reflux will take place. The blood reflux could take place in the atria, or the blood from the heart could be ejected into the pulmonary artery or aorta.

What is the term for cardiac contraction recovery?
i did not understand your question well, but there are three wave in working heart i a second: 1-P wave:its about 0.1 second and contraction of the Atriums 2-QRS wave: its about 0.4 second and contraction of the bellies. 3-T wave:its about 0.5 second and relaxing of the heart..
What does the t wave do?
The T wave represents ventricular repolarization in the heart's electrical cycle. It indicates the recovery of the ventricles, preparing them for the next contraction. Changes in the T wave can sometimes signify heart abnormalities.
What does the R wave represent?
The R wave in an electrocardiogram (ECG) represents the depolarization of the ventricles in the heart. It is a measure of the electrical activity during the contraction phase of the heart's pumping cycle.
Which wave length is larger atrial contraction or ventricular contraction?
the ventricular contraction wave is larger
What does the pqrs wave mean?
The PQRS wave represents the electrical activity in the atria of the heart during an electrocardiogram (ECG). The P-wave indicates atrial depolarization, which is the contraction of the atria.
What causes a QRS wave?
A QRS wave is caused by the depolarization of the ventricles of the heart, which leads to the contraction of the ventricles and the pumping of blood out of the heart. The QRS complex represents the electrical activity associated with this depolarization.
Which wave is larger the one for atrial contraction or the one for ventricular contraction?
The wave for ventricular contraction is larger than the wave for atrial contraction. This is because the ventricles have thicker muscle walls and contract more forcefully in order to pump blood out to the body.
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.
The p wave on an ecg is described as a positive deflection that corresponds to what?
The P wave corresponds to the atrial contraction... the 'beat' of the upper chambers of the heart. The QRS complex correponds to the ventricular contractoins.. the 'beat' of the other two chambers. The T wave represents relaxation of the heart muscle.
