When the septum inflates during systole, its internal diameter increases, allowing more wire to be wrapped around it. This squeezes the ventricles to eject blood, like a natural heart.

Data were acquired with ECG gating to diastole and to systole, with and without ARF excitation. From these data, temporal profiles of displacement, crosscorrelation coefficient (CC), and ...

The aorta represents a complex organ system which begins in the aortic ring adjacent to the aortic root with the origin of the two major coronary arteries, and ends at the iliac bifurcation. The ...

Systole has little effect on diastolic coronary artery blood flow. S A Katz; and ; E O Feigl; S A Katz. S A Katz. Department of Physiology and Biophysics, University of Washington, Seattle. Search for ...

Background: Prolonged steady state exercise can lead to a decrease in left ventricular (LV) function as well as promote the release of cardiac troponin T (cTnT). There is limited information on the ...

This cross-journal Collection welcomes submissions focused on unmet needs in heart failure and that will improve our understanding of, or address, health ...

Blood pressure involves two measurements, systolic and diastolic, which depend on whether the heart muscle is contracting (systole) or relaxed (diastole) between beats. Normal blood pressure is at ...
