4) This manifests in several ways: (i) an increase in cephalad and caudad peak velocities; (ii) spatial inhomogeneity in velocities; (iii) simultaneous bidirectional flow; and (iv) substantial net craniad or caudad flows within particular voxels and sub regions during the cardiac cycle (Figs 4a - d and 5a - f).
9) Functional information cannot be obtained with this imaging technique on most scanners however, some scanners do, however, allow for data acquisition of data during 2 or more phases of the cardiac cycle, though again at the expense of higher radiation dose.
pulse[R], the size of a cell phone that only during treatment is attached to the patient, is synchronized to his cardiac cycle to stimulate the muscles of the calves and thighs to make them contract in the resting phase of the heart.
5 cm beyond the plane of the atrial septum or phasic excursion of the interatrial septum during the cardiac cycle of at least 1.
The resulting samples from different phases of the cardiac cycle can be represented as a multi-slice collection of images, or interleaved into a cinematographical series of images.
The new research offers fresh insights into the role contact force plays in atrial fibrillation (AF) recurrence rates as well as the dynamic behavior of contact force during the cardiac cycle.
The instant wave-Free Ratio (iFR) is calculated during a period in the cardiac cycle when intra-coronary resistance is naturally constant and minimized, similar to what is achieved during hyperemia with vasodilators such as adenosine over the entire cardiac cycle.
The future development in the MDCT hardware which will provide higher spatial resolution and allow motion analysis during the whole cardiac cycle would be more informative for the evaluation of the mechanisms by which myocardial ischemia is provoked in patients with an anomalous origin of the RCA.
Zygote Human Heart 3 makes it easy for graphics designers, scientists and animators to visualize the human heart, from exteriors and cut views of the interior to an accurate animation of the cardiac cycle.
3) While there is appropriate concern about the radiation exposure required to achieve high image quality for this procedure, the use of dose-adjustment during the cardiac cycle (electrocardiographic modulation) should permit a routine decrease of 30% to 50% from current levels.
pulse[R], the size of a cell phone that the patient attaches to his belt for about 45 minutes per treatment, is synchronized to his cardiac cycle to stimulate the muscles of the calves and thighs to make them contract in the resting phase of the heart.
As the relative distribution of potentials on the body surface during repolarization is largely constant in time, changing mostly in the general amplitude, subtle abnormalities of repolarization, as deviations from this normal feature (7), have been described using a singular value decomposition of the series of instantaneous repolarization potentials over the ST-T interval in a single cardiac cycle.
