Figure 2. PP2 inhibits diastolic depolarization in isolated sinus node myocytes.

Figure 2

(A) action potentials were recorded in the same cell incubated with PP2 (1μM, 15–30min) (gray) and washout (black). Removal of PP2 depolarized membrane potential and increased the slow diastolic depolarization. (B) action potentials were recorded in the same cell in the absence and presence of 10nM ISO (grey).
