  1. Comparison of contraction and calcium handling between right and left ventricular myocytes from adult mouse heart: a role for repolarization waveform Volume 571, Issue 1, 131–146, Article first published online: 6 February 2006

There was an error to the errata on page 499 in volume 571, in relation to Kondo et al. (2006), which is corrected below.

The last sentence of page 143 should have read

Thus, our conclusion that AP waveform differences can produce regional variations of myocyte contraction does not rule out contributions from parallel mechanisms involving, e.g. differential phosphorylation.

The publisher regrets this error.
