GNAQ and Ventricular arrhythmia: Table 2 shows the overall data for ventricular arrhythmias. NTG mice did not induce ventricular arrhythmias such as a high PVC count (more than 20 beats/min). In contrast, a high number of PVCs was observed in 9 of 10 vehicle-treated Gαq-TG mice (Table 2). Moreover, non of olmesartan-treated Gαq-TG mice induced a high PVC count, indicating a significant reduction of ventricular arrhythmias in olmesartan-treated Gαq-TG mice compared with that in vehicle-treated Gαq-TG mice.
