Figure 4

Composite data of the effect of chronic amiodarone on basic cycle length (BCL) at which 1:1 activation failure occurred in pulmonary vein (PV) sleeve (n = 5) and left ventricular (LV) wedge (n = 4) preparations isolated from untreated and chronic amiodarone-treated dogs. Chronic amiodarone induced a significant increase in the BCL at which activation failure occurred in PV sleeve and LV wedge preparations, but the effect was much more pronounced in PV sleeves. Data are expressed as mean ± SD. *P < 0.05, chronic amiodarone versus control.
