the atria contracts first then the ventricle hencep qrs
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
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).
Well, it's often referred to as the direction of propagation of the wave.
QRS wave
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?
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.

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..
the ventricular contraction wave is larger
Ventricular contraction wave is larger
The move by expansion and Contraction of the medium by which they are propagated. It is transmitted in air as a longitudinal wave- which means its direction is in line with the movement of the medium.
A longitudinal wave is a wave of which the disturbance direction is the same direction of the direction of the wave. Waves done in a spring and sound waves are an example. A longitudinal wave: | | | | | | | | | | | | | | | | | | | | | | | | |
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.

The p-wave is the atrial depolarization or when the atrium contract to pump blood to the ventricles. The "p-wave" is showing you how the electic current changes while the heart is doing that specific action.
A wave that represents the direction in the direction the wave moves.
In a transverse wave the particle displacement is perpendicular to the direction of wave propagation (at right angles). In a longitudinal wave the particle displacement is parallel to the direction of wave propagation.
