Figure 4. Ppp1r3a-KO mice exhibit increased susceptibility to pacing-induced AF.

Figure 4.

A, Representative recordings of surface ECG lead II showing no change in baseline ECG parameters comparing 4-month old Ppp1r3a-KO mice and WT littermates. B, Simultaneous recordings from surface and intracardiac (atrial and ventricular) leads demonstrating AF in Ppp1r3a-KO mice (right) and normal sinus rhythm in WT littermate (left) following atrial burst pacing. C, Bar graph summarizing the incidence of inducible AF in Ppp1r3a-KO mice. Data were analyzed using Fisher’s exact test (*P<0.05 vs. WT).
