Contractile performance of atrial trabeculas from PAB and sham rabbits. A: active developed force at 1–4 Hz shows near-equal forces at 1 Hz and a significantly higher force at 3 and 4 Hz. B: time-to-peak tension (TTP) was abbreviated with frequency equally in PAB and sham trabeculas. C: relaxation, assessed as time from peak tension to 50% relaxation (RT50) became faster with frequency; no differences were observed between the two groups.
