Individual AF durations. Individual AF durations (>2 s) induced by atrial burst pacing before (A, black) and after perfusion with ICA 1 µM (B, red) at 5 different stretch levels. Top panel shows example of atrial action potential recordings before, during and after burst. Data are presented as box and whiskers with median and 25–75 percentile, n = 13. Note that the Y-axis is logarithmic. mmHg refers to LA balloon pressure.
