Synchronization of Wave Flows of Arterial and Venous Blood with Phases of the Cardiac Cycle in Norm: Part 5 [PDF]
International Journal of Biomedicine, 2022 The muscular-fibrous frame of the heart (MFFH) synchronizes and compensates for the pressor effect of the myocardium between the high/low-energy regions (left/right) of the heart. The anatomical structures of MFFH (plastic muscular-fibrous formation with

Synchronization of Wave Flows of Arterial and Venous Blood and Phases of the Cardiac Cycle: Part 4 [PDF]
International Journal of Biomedicine, 2019 Hemodynamic indices of healthy people obtained by catheterization in such vascular areas as the chambers of the heart (both ventricles, both atria, coronary sinus), IVC, SVC, RHV, right renal vein, sigmoid sinus, and aorta were analyzed.

Synchronization of Wave Flows of Arterial and Venous Blood with Phases of the Cardiac Cycle in Norm: Part 1 [PDF]
International Journal of Biomedicine, 2018 Hemodynamic indices studied in practically healthy people were obtained by catheterization in various vascular areas: the chambers of the heart (left ventricle, right ventricle, left atrium, right atrium, coronary sinus), pulmonary trunk, aorta, inferior

Impact of Cardiac Interoception on the Self-Prioritization Effect
Frontiers in Psychology, 2022 Self-relevant information is processed faster and more accurately than non-self-relevant information. Such a bias is developed even for newly associated information with the self, which is also known as the self-prioritization effect (SPE). Interoception,

Regulatory Synchronization of Hemodynamics of the Heart and Brain in Norm [PDF]
International Journal of Biomedicine, 2019 By catheterization, the integral indicators of synchronization and interaction of blood flows, designated as “venous and arterial boluses,” were obtained, studied and analyzed in healthy people on the pathway: right heart–lung–left heart.

Dynamic cerebral autoregulation across the cardiac cycle during 8 hr of recovery from acute exercise
Physiological Reports, 2020 Current protocols examining cerebral autoregulation (CA) parameters require participants to refrain from exercise for 12–24 hr, however there is sparse objective evidence examining the recovery trajectory of these measures following exercise across the ...

Mechano-electric effect and a heart assist device in the synergistic model of cardiac function
Mathematical Biosciences and Engineering, 2020 The breakdown of cardiac self-organization leads to heart diseases and failure, the number one cause of death worldwide. Within the traditional time-varying elastance model, cardiac self-organization and breakdown cannot be addressed due to its inability

Intraoperative management of critical arrhythmia [PDF]
Korean Journal of Anesthesiology, 2017 The incidence of intraoperative arrhythmia is extremely high, and some arrhythmias require clinical attention. Therefore, it is essential for the anesthesiologist to evaluate risk factors for arrhythmia and understand their etiology, electrophysiology ...

Diagnostics, 2022 We aimed to investigate the relation between the time intervals of the flow velocity waveform of ductus venosus (DV-FVW) and cardiac cycles. We defined Delta A as the difference in the time measurements between DV-FVW and cardiac cycles on the assumption
