Summary LA volume changes during simulated atrial contraction

i	$V_0$ (ml)	$V_{\mathrm{infl}}$ (ml)	$V_{\mathrm{cont}}$ (ml)	IF (%)	EF (%)
1	101.03	156.47	98.81	154.9	36.9
2	61.04	99.31	67.57	162.2	32.0
3	51.11	83.36	62.32	163.1	25.2

i Case index; $V_0$ reference volume; $V_{\mathrm{infl}}$ volume after inflation, prior to atrial contraction; $V_{\mathrm{cont}}$ minimum atrial volume at contracted state; inflation fraction (IF) is $V_{\mathrm{infl}}/V_0$; and ejection fraction (EF) is ($V_{\mathrm{infl}}-V_{\mathrm{cont}})/V_{\mathrm{infl}}$
