Impact of PAC burden on survival, CV hospitalization, new-onset AF, and PPM implantation. A, Patient survival of PAC ≤76 beats per day group compared with PAC >76 beats per day group (P<0.001 by log-rank test). B, Patient CV hospitalization-free survival of PAC ≤76 beats per day group compared with PAC >76 beats per day group (P<0.001 by log-rank test). C, Patient AF-free survival of PAC ≤76 beats per day group compared with PAC >76 beats per day group (P<0.001 by log-rank test). D, Patient PPM-free survival of PAC ≤76 beats per day group compared with PAC >76 beats per day group (P<0.001 by log-rank test). E, Patient survival of PAC burden in quartile comparison (P<0.001 by log-rank test). F, Patient CV hospitalization-free survival of PAC burden in quartile comparison (P<0.001 by log-rank test). G, Patient AF-free survival of PAC burden in quartile comparison (P<0.001 by log-rank test). H, Patient PPM-free survival of PAC burden in quartile comparison (P<0.001 by log-rank test). *P<0.05 in comparison with Quartile 1; †P<0.05 in comparison with Quartile 2; ‡P<0.05 in comparison with Quartile 3. AF indicates atrial fibrillation; CV, cardiovascular; PAC, premature atrial complex; PPM, permanent pacemaker.
