Of hearts that did experience VT or VF, the time between diamide administration and the first incidence of arrhythmia was also not significantly shorter in Scn1a−/+ mice (15.53 ± 4.43 in Scn1a+/+ vs. 10.38 ± 2.78 in Scn1a−/+; p = 0.70) (Fig. 8B). The gene discussed is SCN1A; the disease is Arrhythmia.
