Heart Vector Origin Point Detection and Time-Coherent Median Beat Construction

Erick Andres Perez Alday, Larisa Tereshchenko

The algorithm finds the heart vector origin point and constructs the time-coherent median beat. VCG origin point is defined as the electrically quiet or isoelectric state of the heart when the heart vector does not move in 3D space.

Influence of the MHD effect on 12-lead and 3-lead ECGs recorded in 1T to 7T MRI scanners

Johannes W Krug Passand

ECG signals were acquired in various MRI scanners to enable the study of the magnetohydrodynamic (MHD) effect. The MHD effect, which is caused by an interaction of the blood flow and the MRI’s high static magnetic field, superimposes the ECG signal.

Effect of 24-hour sleep deprivation on cerebral hemodynamics and cognitive performance

Peter Mukli, Andriy Yabluchanskiy, Tamas Csipo

We assessed the impact of 24-hour sleep deprivation on the global properties of frontal lobe functional networks and on cognitive performance. fNIRS measurements were carried out in the resting state and in response to a finger-tapping paradigm.
