Figure 3. AF inducibility by age. (A) Percent of mice in sinus rhythm (blue) and AF (red) in Sham (n = 14) and THOR (n = 33) mice in the bottom age tertile. (B) Percent of mice in sinus rhythm (blue) and AF (red) in Sham (n = 14) and THOR (n = 34) mice in the middle age tertile. (C) Percent of mice in sinus rhythm (blue) and AF (red) in Sham (n = 17) and THOR (n = 20) mice in the oldest age tertile. AF was defined as at least two (out of three) positive AF events after the A-burst protocol. P values were obtained from chi-square tests. *P < 0.05. P ≥ 0.05 denoted ns. AF: Atrial fibrillation; SR: sinus rhythm.
