SL and its changes (ΔSL) in RVCM and LVCM. (A–C) Summaries comparing the diastolic SL (A), the ΔSL (B), and the percent ratio of ΔSL/diastolic SL in each cell (C). (D and E) Time to relax₁₀, relax₅₀, and relax₉₀ representing the time from peak to 10, 50, and 90% relaxation of ΔSL, respectively. 20 animals were used for measuring contraction and are depicted individually.
