Forward flow across the isthmus throughout the cardiac cycle (including diastole) is characteristic (Figure 18).

Background— The phase difference of coronary arterial and venous flows indicates the importance of intramyocardial capacitance vessels in storing diastolic flow and in discharging volume in systole.

The objective of this paper was to investigate texture feature variability in ultrasound video of the carotid artery during the cardiac cycle in an attempt to define new discriminatory biomarkers of ...

Diastole and systole are two phases of the cardiac cycle. They occur as the heart beats, pumping blood through a system of blood vessels that carry blood to every part of the body. Systole occurs ...

The cardiac cycle is a precise sequence of events the heart muscle performs during each heartbeat. A single cardiac cycle consists of two components— systole and diastole. Systole occurs when the ...

Learn more about systolic and diastolic heart failure, which both affect the left side of the heart muscle. Explore similarities and differences.

Aims Blood pressure (BP) is a crucial factor in cardiovascular health and can affect cardiac imaging assessments. However, standard outpatient cardiovascular MR (CMR) imaging procedures do not ...

Pulse pressure is the difference between systolic and diastolic blood pressure readings, indicating potential health conditions.

Description The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next. It consists of two periods: one during which the heart muscle ...

Mean arterial pressure (MAP) is a key reading doctors use to assess blood flow through your body. It’s related to your systolic and diastolic blood pressure readings but accounts for flow and ...
