Following publication of the original article [1], the author noticed the error in Fig. 6. In the published article, Figs. 4 and 6 look same. The author has wrongly uploaded Fig. 6 in the manuscript package which has been processed by the typesetter. However, the text citations and caption of Fig. 6 seems to be correct. Now this has been corrected with this erratum. The corrected Fig. 6 has been given in this correction.

Assessment of [Ca2+]SR by measurement of caffeine-induced CaTs. a Representative recording of caffeine-induced CaTs from a single RVCM for the 4 groups (caffeine = 10 mmol/L), which was used to estimate the total [Ca2+]SR content. b CaT amplitude. c CaT decay time constant. Each point represents the result from a single RVCM. RVCM right ventricular cardiomyocyte, CaT Ca2+ transient, [Ca2+]SR sarcoplasmic reticulum Ca2+ content. n/N = 15/5 = cells/rats per group. The horizontal lines show the mean ± SEM. One-way ANOVA or the nonparametric Wilcoxon signed-rank test. *p < 0.05, **p < 0.01, ***p < 0.001
