Comparison of ventricular fibrillation thresholds (n = 7). To confirm the benefits of Wenxin Granule treatment for mitigating potentially lethal arrhythmias following myocardial infarction (MI), programmatic electrophysiological stimulation was performed 2 weeks after MI in vivo. (a) The compressed waveform of the epicardial electrogram recording and the expanded waveform. (b) Comparison of ventricular fibrillation threshold values, expressed as the mean ± SD. A: sham operation group; B: model group; C: low-dose Wenxin Granule group; D: high-dose Wenxin Granule group; E: metoprolol group. , ^∗P < 0.05, ^∗∗P < 0.01 compared with the sham operation group, ^#P < 0.05, ^##P < 0.01 compared with the model group.
