Figure 2

(a) Mean PVC burden during 24-hour Holter monitoring at 0, 4, and 8 weeks in the SSYX and placebo groups. PVC: premature ventricular contraction. (b) Mean heart rates at 0, 4, and 8 weeks between SSYXC and placebo groups. SSYXC: Shensong Yangxin. (c) Subgroup analyses on reduction in PVC burden after 8 weeks of treatment of SSYX stratified according to age, PVC burden, and MHR. MHR: mean heart rate; PVC: premature ventricular contraction; SSYXC: Shen song Yangxin. (d) Subgroup analyses on increase in MHR after 8 weeks of treatment of SSYX stratified according to age, PVC burden, and MHR. MHR: mean heart rate; SSYXC: Shensong Yangxin. (e) Average symptom score 0, 4, and 8 weeks in SSYX and placebo groups. SSYXC: Shensong Yangxin.
