Figure 2.
Whole-cell patch-clamp recordings of KATP currents from dog atrial myocytes. (A) Time courses of whole-cell KATP currents induced by metabolic inhibition (above, MI, 10 mM deoxyglucose + 10 mM NaCN), 100 µM pinacidil, and 100 µM diazoxide from right atrial myocyte. (below) Raw traces from the time points indicated above. (B) Summary of KATP currents in dog atrial myocytes. MI and pinacidil (Pina) activate comparable currents from dog atrial myocytes.
