Table 1.
Preload, mmHg | iCSΔBmal1+/+ | iCSΔBmal1−/− |
---|---|---|
10 | 0/7 | 0/6 |
12.5 | 0/7 | 1/6 |
15 | 0/7 | 3/6 |
20 | 2/7 | 5/6 |
Conduction block/delay is more common in iCSΔBmal1−/− mice with increased preload. The occurrence of conduction block/delay in the iCSΔBmal1+/+ and the iCSΔBmal1−/− in ex vivo working heart preparations is summarized as the number of hearts showing conduction block/delay over the total number of hearts tested for each group.
