Heart rate (bpm) changes measured by echocardiography.

The heart rate of Sham group was 259±30 bpm (beat per minute).
Ctrl+MI+Tri-P, control pretreated rat with Tri-cell patch graft; miR-29b+MI+Tri-P, miR-29b mimic pretreated rat with Tri-cell patch graft; Anti-29b+MI+Tri-P, miR-29b inhibitor pretreated rat with Tri-cell patch graft. All values were expressed as mean ± SEM. n = 6 for each group.

假手术组（Sham group）的心率为259±30 次/分钟（beat per minute，bpm）。
Ctrl+MI+Tri-P：经Tri细胞补片移植（Tri-cell patch graft）预处理的对照组大鼠；miR-29b+MI+Tri-P：经Tri细胞补片移植预处理并转染miR-29b模拟物（miR-29b mimic）的大鼠组；Anti-29b+MI+Tri-P：经Tri细胞补片移植预处理并转染miR-29b抑制剂（miR-29b inhibitor）的大鼠组。所有实验数据均以均值±标准误（Standard Error of the Mean，SEM）表示，每组样本量为6只。
