Effects of hyposmotic cell swelling on action potential in mouse ventricular myocytes
| Resting potential (mV) | APD (ms) | APD25 (ms) | APD75 (ms) | APD90 (ms) | |
|---|---|---|---|---|---|
| Isosmotic | − 69.5 ± 1.6 | 95.1 ± 9.8 | 2.7 ± 0.5 | 18.0 ± 4.4 | 45.2 ± 7.9 |
| Hyposmotic | − 68.5 ± 1.2 | 58.4 ± 8.8** | 1.8 ± 0.4* | 13.7 ± 5.1* | 25.3 ± 7.0** |
P < 0.05
P < 0.01 versus isosmotic (n = 5).
