- Specialized
- Understanding the cardiac cycle is essential for diagnosing heart diseases and ensuring proper treatment.
- phase of the cardiac cycle
Examples
-
However, this issue has not been sufficiently investigated by non-invasive techniques because of right ventricular complex geometry, which hinders an accurate assessment of right ventricular internal chamber dimensions and their changes during the cardiac cycle.

As measured on the skin, the cardiac cycle creates the peaks and valleys seen on a typical electrocardiograph.

However, it is difficult to automatically detect the abnormal flow based on the flow pattern because it is temporally changing during a cardiac cycle.

In addition, the number of the generated flowlines varies because the prevalence of the reversed flows during a cardiac cycle can also vary.

The first and second datasets consist of flow data with 120 frames that are spaced 8 msec apart during a cardiac cycle.

Fig. 2 depicts a signal, a shape representing the successive depolarization and repolarization in each cardiac cycle.

In the systolic (or pumping) phase of the cardiac cycle, the left ventricle pushes out about 60% or more of the blood it holds into the systemic circulation.

Mean arterial blood pressure (MAP, mmHg), representing the average arterial pressure during the cardiac cycle, was calculated as DBP + (SBP - DBP) / 3.

The unidirectional tracing showed that the line generation rate varied according to the phase of a cardiac cycle, i.e., a high rate in systole and a low rate in diastole, as depicted in Fig. 11.

The cardiac cycle consists of a series of events that control the heart's pumping action.

Morphology
The meaning 'the sequence of events in the heart' is directly and transparently derived from combining 'cardiac' (related to the heart) with 'cycle' (a repeating sequence). This compositional pattern is common cross-linguistically (e.g., Spanish 'ciclo cardíaco', French 'cycle cardiaque') and, despite being a technical term, would be understandable to a B1 learner who knows both constituents.
Etymology
Cardiac cycle joins cardiac (about the heart) and cycle (a repeated round). Picture the heart doing one full round—squeeze, then relax—and starting again; that's why it means 'the events from one heartbeat to the next'.
