Cardiac Cycle: The sequence of events in a single heartbeat, including contraction (systole) and relaxation (diastole) of the heart. This Nature Research Intelligence Topic summary is one of ...

Transthoracic echocardiography showed a hyperdynamic left ventricle with symmetric wall thickening (17 mm), systolic intracavitary ... wall throughout the cardiac cycle) showed not only severe ...

Left ventricular stiffness and contractility, characterized by the end-diastolic pressure-volume relationship (EDPVR) and the end-systolic pressure-volume ... the amount of blood pumped by the LV per ...

Simply, the “cardiac cycle” is a way doctors have of dividing the work of the heart into two phases — the diastolic phase and the systolic phase. During the diastolic phase of the cardiac cycle, the ...

IABP systems are typically inserted within the multidisciplinary environment that is the cardiac ... pressure Diastolic pressure augmentation is typically greater than systolic pressure reduction ...

the diastolic size appears to remain remarkably constant during a major portion of the diastolic period and (3) residual blood remains within the ventricle at the end of systole.

However, if the stimulation signals are always applied when the heart is contracting (during systole), a strong effect can be observed – much stronger than if stimulation is applied during the ...

The post-systolic index, which is calculated from a ratio—([peak post-systolic strain]−[end-systolic strain])/(peak strain or maximum strain change during the cardiac cycle)—is widely ... peak ...

The adequacy of RV systolic functional adaptation to increased afterload ... Relative changes in RV volume during a cardiac cycle were calculated from the Doppler flow velocities (figure 6). The ...

Heart rate (HR) has an impact on the central blood pressure (BP) wave shape and is related to pulse wave velocity and therefore to timing and duration of systole and diastole ... becomes reduced with ...
