Contraction-relaxation kinetics of the LV chamber. A) Representative examples of an absolute time-varying elastance (left) and an amplitude normalized time-varying elastance (right) of WT (solid lines) and TtnΔC1−2 (broken lines) mice. The onset of ejection and the end-systole are indicated. B) The peak elastance at end systole (Ees) is reduced in the TtnΔC1−2 mice. C) The time to onset of ejection (Toe:left),the time to end systole (Tes:middle), and the ratio of elastance at the onset of ejection relative to at the end systole (Eoe/Ees:right) are not different between genotypes. D) The time to 50% elastance decay is prolonged in TtnΔC1–2. n= 7–8 mice per group. Each data point represents a single mouse. Mean ± S.E.M are shown. Mann Whitney test: ***P < 0.001.
