What part of an ecg do atria contract?

Atrial depolarization occurs at the P wave. The atrial contraction occurs at the peak of the wave at the influx of calcium ions to prolong depolarization.

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.

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.

Depolarization of the atria corresponds directly to the EKG's?

P wave

The p wave corresponds to depolarization of the muscle fibers of the?

The p wave on a heart telemetry monitor represents the depolarization of the atria of the heart.

What is polarization in the electrocardiogram?

The contraction of any peart of heart in ecg is known as polarization. Eg contraction of atria is known as polarization of atria

What are the function of the valves?

In cardiovascular health, heart valves are located between atria and ventricles in the heart. The valves will open significantly during the atrial depolarization, or contraction of the atria. During the subsequent re-polarization of the atria and depolarization of ventricles, the valves are pushed in the opposite direction and shut closed. This mechanism allows the flow of blood in one single direction only, from atria to ventricle.

In a normal ECG tracing?

the repolarization of the atria is hidden by the QRS wave

The node that directly controls contraction of the atria is?

Sinoatrial node

Period of heart contraction?

Contraction of the ventricles and atria is called systole. Relaxation is called diastole.

What is the P wave of electrocardiogram closely followed by?

Contraction of both atria

Is systolic pressure where the ventricls are relaxing?

Relaxation = Diastole Contraction of the atria=Atrial systole Contraction of the ventricles = Ventricular systole
