  "main_findings": "In hens, the ventricular epicardium recovery sequence appeared independent of the activation sequence and was described as governed by activation-recovery intervals. The inversion of positive and negative areas on the body surface corresponded to the end of the QRS complex and the beginning of the ST-T complex.",
