Kết quả khử cực kích hoạt các cảm biến điện áp và mở kênh, cho phép thông qua ion. Sau đó để kích hoạt kênh, các kênh vào trạng thái bất hoạt không dẫn điện và vật liệu chịu lửa. Tái cực là cần thiết để giảm bớt bất hoạt với thời gian isoformspecific và phụ thuộc vào điện áp. | Pacemaker Current and Automatic Rhythms Toward a Molecular Understanding 65 Boyett MR Dobrzynski H Lancaster MK Jones SA Honjo H Kodama I 2003 Sophisticated architecture is required for the sinoatrial node to perform its normal pacemaker function.
