There is a lot of uncertainty in the theory of hemodynamics: The amount of work need to displace the blood in the systemic circulation, exceeds the work done by the left ventricle.

Blood flow acceleration increases from the left ventricular outflow tract to the sinotubular junction and the ascending aorta, while it must be decreasing due to the turbulences. With this, blood recovers increased flow resistance between the heartbeats with the Womersley number alterations in the rhythm of the accompanying ECG. Viscoelastic transformation is heavily expressed in coagulation. There must be a relationship between the ECG and blood transient flow resistance.

Was studied the influence of the electromagnetic field on blood flow and coagulation. Venous blood was affected by the oscillated electromagnetic field (500-5000Hz.), with the square wave input signal in 25 healthy individuals.

Was revealed to decreased flow resistance and hypocoagulation in normal blood samples, and thrombolysis after the blood stasis. 

Ac electric field from the myocardial depolarization initiates electroacoustic phenomena. An emerging repulsing electromagnetic force acts on the RBC and in addition to the pulse pressure from the heart, promotes blood motion and viscoelastic changes.

The alterations of the blood inertial and elasticity, in addition to hemodynamics, are facilitated by the magnetic features of the hemoglobin.

Although electromagnetic influence is carried out on the arterial and venous blood, structural changes with the increasing entropy are specified only for the pulsatile blood. It must be associated with the frequency dispersion of the substance at the boundary reflection and activation of the coagulative system at the low shear velocity in the vena.

The external electromagnetic signal can manage the blood coagulation process, including thrombolysis.
