Systole and diastole are two phases of the cardiac cycle. During diastole, the heart is expanded and it fills with blood. During systole, the heart...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
Mean native T1 values were not significantly different when measured in systole and diastole (985±26ms vs 988±29 respectively;=0.061) and mean post-contrast values showed similar good agreement (462±32ms vs 459±33 respectively,=0.052). No clinically significant differences in ECV, native T1...

By means of a specially designed stimulator-triggered freeze clamp, hearts were terminated at systole and diastole, and tissue content of ATP, ADP, AMP, adenosine, phosphocreatine, creatine, pyruvate, lactate, and inorganic phosphate were analyzed. A 50% reduction in cardiac performance of the ...
(RRI), pulse transit time (PTT), and pulse interval (PPI). The latter two quantities depend on the method to identify pulse cycle limits, e.g. to detect systolic peaks (p), points of maximum slope or 1st derivative (d), or diastolic minima/foot points denoting the onset of systole (...

Contrary to systole duration (HYV: 360 ± 29 ms; HEV: 364 ± 47 ms), diastole duration presented higher inter-individual variability in both populations (HYV: 472 ± 145 ms; HEV: 456 ± 106 ms). Our results also showed that, with age, it is mainly the diastolic phase that changes....
