Electromagnetic properties of the arterial blood flow

Abstract

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 flow turbulences in the Valsalva sinuses and increased diameter of the vessel. Total energy of the pulse wave in the arterioles is up to 7.2 times higher, than in the ascending aorta, while it must be low due to the energy dissipation in the viscous flow, with the distance from the heart. Purpose of the study is identifying the additional possible energy source, for the arterial blood flow.Methods and materials: 12 healthy volunteer students (male) underwent echocardiography, ECG gated MRI of the heart for the visualization intracavitary flow in the ventricles, MR Angiography of the aorta. Blood flow velocities and acceleration were studied in the different sites of the heart and the aorta. Results: With the DU in the left ventricular outflow tract blood acceleration is 1430 ± 120 cm/sec 2 , in the sinotubular junction and ascending aorta 2395 ± 195cm/sec 2 , at the aortic arch 1390 ± 225cm/sec 2 , isthmus of aorta 2180 ± 135cm/sec 2 , middle thoracic aorta1260 ± 140m/sec 2 . With the MRI (TrueFisp. Mean curve), blood acceleration from the left ventricular outflow tract to the sinotubular junction is 3.5 ± 0.3 times higher and to the ascending aorta 2.5 ± 0.2 times higher. Systolic blood pressure from the ascending aorta to the femoral and saphenous elastic arteries enhancing 1.3 ± 0.1 times, increasing energy transmitted to the blood. Direction of the electric charge in the heart's ventricles from the circulating erythrocytes and in the fibers of the Purkinje (ECG), mathematically are coincident.Conclusion: Availability of the heart, as the possible single tool for the blood flow, looks imperfect. Electric oscillate field from the heart dipoles can be impact to the erythrocytes, forming the modulated naturally ultrasound vibration and associated with it colloid vibration current propagating distally to the all cell membranes. Blood motion in the heart chambers and arteries has the additional basis, besides the heart contraction: rotating blood particles in the heart chambers and in the arterial branching sites, with the concomitant oscillating electric field triggered from the heart, forms additional electromagnetic repulsing force for the charged particles, providing to the flow. Modulating ac electric field, transmitting by the oscillate blood particles, besides the flow, creates additional energy/signal source, enabling the spontaneous chemical reactions proceed across the cell membranes.

“…The system is on its way for clinical testing and validation on different human subjects. Therefore, at the next step, efforts are to develop a cuff less continuous BP device [15][16][17].…”
