Figure 2. Effects of chromanol 293B on ventricular action potentials in the absence and presence of β-adrenergic stimulation in control male and female rabbits.

Figure 2

A–B, Shown are representative AP’s recorded in LV myocytes from a control female (A) and a control male rabbit (B) with and without 10 μM chromanol 293B (IKs blocker) at a cycle length of 1000 ms. C–D, Representative AP’s recorded in myocytes from a control female (C) and a control male (D) rabbit at baseline, in the presence of 500nM ISO, and after 500nM ISO + 10 μM chromanol 293B (all at a cycle length of 1000 ms).
