Several equations in our recent article contain minor errors. The correct equations are listed below. The data were not affected, except for the calculated Extension at the L-type Ca²⁺ channel, which becomes 2.5 μm instead of 3.3 μm s (Table 1). This difference does not affect the conclusions of the article. The authors regret the errors.
