A, bath application of nifedipine (1 μm) led to membrane depolarization of 3.3 ± 0.4 mV over control (P < 0.05, n = 3) and elimination of spontaneous action potentials. B, snapshots of original recordings from A on an expanded time scale before and after application of nifedipine. Note that small upward deflections in original recordings are due to perfusion pump noise.
