Table 1 shows the overall data for ventricular arrhythmias. Ventricular arrhythmias such as a high PVC count (more than 20 beats/min) were not observed in WT and nicorandil-treated WT mice. In contrast, a high number of PVCs was observed in 7 of 10 vehicle-treated Gαq-TG mice (Table 1). Interestingly, a high PVC count was not observed in any nicorandil-treated Gαq-TG mice tested, indicating a significant reduction of ventricular arrhythmias in nicorandil-treated Gαq-TG mice compared with vehicle-treated Gαq-TG mice. The gene discussed is GNAQ; the disease is Ventricular arrhythmia.
