Delineation and Analysis of Seismocardiographic Systole and Diastole Profiles [PDF]
IEEE Transactions on Instrumentation and Measurement, 2020 Precise estimation of fiducial points of a seismocardiogram (SCG) signal is a challenging problem for its clinical usage. Delineation techniques proposed in the existing literature do not estimate all the clinically significant points of an SCG signal ...

Cerebral arterial flow dynamics during systole and diastole phases in young and older healthy adults
Fluids and Barriers of the CNS, 2023 Background Since arterial flow is the leading actor in neuro-fluids flow dynamics, it might be interesting to assess whether it is meaningful to study the arterial flow waveform in more detail and whether this provides new important information.

Modelling of fibre dispersion and its effects on cardiac mechanics from diastole to systole
Journal of Engineering Mathematics, 2021 Detailed fibre architecture plays a crucial role in myocardial mechanics both passively and actively. Strong interest has been attracted over decades in mathematical modelling of fibrous tissue (arterial wall, myocardium, etc.) by taking into account ...

Estimation of End-Diastole in Cardiac Spectral Doppler Using Deep Learning
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2020 Electrocardiogram (ECG) is often used together with a spectral Doppler ultrasound to separate heart cycles by determining the end-diastole locations. However, the ECG signal is not always recorded.

Inotropic interventions do not change the resting state of myosin motors during cardiac diastole
The Journal of General Physiology, 2018 &NA; When striated (skeletal and cardiac) muscle is in its relaxed state, myosin motors are packed in helical tracks on the surface of the thick filament, folded toward the center of the sarcomere, and unable to bind actin or hydrolyze ATP (OFF state ...

Recognizing End-Diastole and End-Systole Frames via Deep Temporal Regression Network
International Conference on Medical Image Computing and Computer-Assisted Intervention, 2016 Accurate measurement of left ventricular volumes and Ejection Fraction from cine MRI is of paramount importance to the evaluation of cardiovascular functions, yet it usually requires laborious and tedious work of trained experts to interpret them.

NOVEL UNDERSTANDING OF THE PHASIC STRUCTURE OF SYSTEMIC CIRCULATION
Российский кардиологический журнал, 2014 The article provides novel approach to the phasic structure of systemic circulation for rheovasogramms of upper and lower extremities, based upon neither geometrical description with visual evaluation of rheographic complexes, but upon genesis of their ...
