1·As a result single guinea-pig atrial myocyte with normal electrophysiologic activity was obtained and its L-Ica and IK were successfully recorded with patch-clamp technique.

结果获得了具正常电生理活性的单个细胞及高阻封接的形成，成功记录了L -型钙流和延迟整流性钾流。

2·The atrial cell membrane capacitances were read directly in patch -clamp.

全细胞电压膜片钳测定心房细胞的膜电容表示心房细胞的大小。
