WebThe data concerning systolic or diastolic duration from three in vivo studies were included in Figure 1. Husmann et al. found that the length of systole shortened from 400 to 360 ms, respectively, for 45 to 100 bpm.

WebContraction of the heart muscle is known as systole and relaxation of the heart muscle is called diastole. The cardiac cycle has 3 stages: WebThe filling pattern is divided into three phases: a dominant systolic phase, a diastolic phase, and a third short atrial contraction phase with small reversal (upstream) flow from the RA into the systemic veins. During diastole the tricuspid valve opens, and blood from the RA is drained into the RV in two phases, early and late diastolic filling.
