The largest wave is the R
Assuming you are talking about Electrocardiogram readings, the ventricular contraction is represented by the 'R' wave. The R wave is so much higher because the left and right ventricles are made up of the largest and strongest muscles of the heart and show the largest electrical energies on the ECG when they are contracted.
Atrial Depolarization.
p wave
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
Contraction of both atria
yes
Repolarization of ventricular muscle fibers.
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.
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.
The P wave refers to the electrocardiographic representation of electrical activation of the atrial myocardium. It can be measured using an electrocardiogram.
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.
no it is not the largest.
