Action potential durations recorded by current-clamp mode of a mouse HL-1 cardiomyocyte at various times after added LPS endotoxin (S. enteritidis; blue) compared with controls (untreated and added 10 ng/ml LBP; black) as in Fig. 2. A: action potential duration at 50% repolarization. B: action potential duration at 75% repolarization. Box and whisker plots: ■, mean; T-bars, minimum and maximum; box, 25th percentile, median, and 75th percentile; n = 10.
