ventricular systole

This is the second phase and is called "ventricular systole".

During ventricular systole, pressure rises in the left ventricle.

Ventricular systole induces increased pressure in the left and right ventricles.

Ventricular systole is the origin of the pulse.

This is what makes ventricle contraction take place and makes ventricular systole.

Prolapse of the mitral valve into the left atrium during ventricular systole.

This allows the blood to be ejected from the left ventricle into the aorta during ventricular systole.

The increased blood volume in the right ventricle causes the pulmonic valve to stay open longer during ventricular systole.

Right ventricular systole drives blood through the pulmonary valve (PV) into the lungs.

Ventricular systole is the contraction of the muscles (myocardia) of the left and right ventricles.

Then ventricular systole happens.

Even though the atrial systole comes before ventricular systole, all four chambers do diastole at the same time.

The order is: atrial systole ventricular systole cardiac diastole.

The papillary muscles of both the right and the left ventricles begin to contract shortly before ventricular systole and maintain tension throughout.

It is caused by blood flowing backwards into the jugular vein through the incompetent tricuspid valve during ventricular systole.

After ventricular systole, the pressure in the left ventricle decreases as it relaxes and begins to fill up with blood from the left atrium.

In human physiology, the atria facilitate circulation primarily by allowing uninterrupted venous flow to the heart during ventricular systole.

The reduced volume in the right ventricle allows the pulmonic valve to close earlier at the end of ventricular systole, causing P2 to occur earlier.

This procedure involves wrapping the latissimus dorsi muscles around the heart and electrostimulating them in synchrony with ventricular systole.

The murmur is heard due to antegrade flow of blood through a progressively narrowing mitral opening during the end of the ventricular systole.

It appears to "function as a decompression chamber during left ventricular systole and during other periods when left atrial pressure is high".

The Time variable of right ventricular systole is PV open to PV close.

That is what makes the ventricular systole occur after atrial systole, and lets all the blood leave the atria before ventricle contracts (meaning squeeze).

In normal individuals, during ventricular systole, the pressure in the ascending aorta and the left ventricle will equalize, and the aortic valve is open.

It is important to note that cardiac muscle perfusion through coronary vessels does not occur during ventricular systole, but occurs during ventricular diastole.
