Table 1.

Conduction block/delay in iCSΔBmal1+/+ and iCSΔBmal1−/− mice

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.
