Effect of amiodarone on [Ca2+]i. Basal [Ca2+]i was measured in HTC cells
| Basal [Ca2+]i (nm) | Δ[Ca2+]i (nm) | |
|---|---|---|
| Control | 91.9 ± 4.9 (n = 19) | 10.7 ± 0.9 (n = 16) |
| Amiodarone treatment | 94.4 ± 5.3 (n = 13) | — |
The Δ[Ca2+]i is the change 5 min after acute exposure to 50 μm amiodarone. Basal [Ca2+]i was also measured after overnight treatment with amiodarone (50 μm). n is the number of cells.
