Unloaded intact cardiac myocytes

Treatment SLr of intact cardiac myocytes (µm) 
Control 1.84 ± 0.003 (n = 268) 
30 mM BDM 1.90 ± 0.003 (n = 101)a 
22.5 µm blebbistatin 1.93 ± 0.005 (n = 172)a 
Treatment SLr of intact cardiac myocytes (µm) 
Control 1.84 ± 0.003 (n = 268) 
30 mM BDM 1.90 ± 0.003 (n = 101)a 
22.5 µm blebbistatin 1.93 ± 0.005 (n = 172)a 

Resting SL (SLr) measurements of intact unloaded cardiomyocytes. The resting SL (mean ± SE) of cardiocytes was measured for unloaded cells with no inhibitor (control), treated with BDM, or treated with blebbistatin. See text for details.
