Fig. 8.

AF duration increases with stretch. Total AF duration recorded at the different stretch levels before (black) and after ICA 1 µM (red). A positive linear correlation was found for the effect of stretching the left atrium and the AF duration (insert formula) at baseline. The two linear regressions (stretch and AF duration (baseline) vs stretch and AF duration (ICA) are significantly different. n = 13. mmHg refers to LA balloon pressure.
