Physiological biomarker ranges for AP and calcium transient characteristics in human epicardial ventricular myocytes
| Biomarker | Minimum Value | Maximum Value |
|---|---|---|
| APD50, ms | 110 | 350 |
| APD90, ms | 180 | 440 |
| CTD50, ms | 120 | 420 |
| CTD90, ms | 220 | 785 |
| RMP, mV | −95 | −80 |
APD50 and APD90, action potential (AP) duration at 50% and 90% repolarization, respectively; CTD50 and CTD90, Ca2+ transient duration at 50% and 90% decay, respectively; RMP, resting membrane potential.
