Abstract
Introduction. Atherosclerosis is the main reason of cardiocerebral events, its mechanisms and reasons are still being studied. Hydraulic shock in arrhythmias has not been studied before.
Aim. To perform the modeling of hydraulic shock as a risk factor of the main arteries in arrhythmias with original experimental model created by the authors.
Materials and methods. We created the original experimental model, it was used to imitate hydraulic shock in arrhythmias. It imitated the real arterial vessel and it allowed to make intra-vessel circulation of liquid in the regular rhythm and in arrhythmias (extrasystole).
Results. In extrasystolic arrhythmia imitation in the first post-extrasystolic contraction the speed of liquid flow was revealed to rise in mean value 158% in comparison with the regular rhythm.
Conclusion. In extrasystolic arrhythmia during the spread of the wave of the first post-extrasystolic contraction, blood flow accelerates and reflected waves and standing waves form. These hemodynamic changes are characterized by the term “hydraulic shock”. The use of our original experimental model helps to make the wide range of investigations and studies connected with intra-arterial hemodynamics in different conditions of functioning of cardiovascular system.
