WebBackground: Post-systolic shortening (PSS) is often detected in heart failure patients, but the effects of cardiac resynchronization therapy (CRT) on PSS remain unknown. We investigated the alterations of PSS by CRT using tissue Doppler imaging and explored the relation to CRT responses. Web19 Oct 2024 · The PSI is associated with most validated echocardiographic and invasive measures of cardiac systolic and diastolic function and was associated with invasively measured LV pressure decline in early diastole and dP/dt min. Post-systolic shortening (PSS) does not contribute to the ejection of blood and may inhibit diastolic filling. We …
