(A) Time-course changes of LPLs levels in whole-ventricular myocardia along with the development of arrhythmias in ouabain-simulated SUD. Salt: rats sacrificed by cervical dislocation in 30 min after saline injection (n = 5). Oua-I°II°: ouabain-induced I°–II° atrioventricular block lasting 30 min and sacrificed by cervical dislocation (n = 5). Oua-III°30 s: ouabain-induced III° atrioventricular block lasting 30 s and sacrificed by cervical dislocation (n = 5). Oua-III° > 30 s: ouabain-induced III° atrioventricular block lasting longer than 30 s before asystole (n = 7). (B) Time-course changes of LPLs levels in whole-ventricular myocardia with electric shock via left upper-right lower limbs current path or lower-lower limbs current path (n = 5 in each group). (C) LPLs levels in ventricular myocardia in left coronary artery occlusion-induced myocardial ischemia (n = 4–7 in each group). (D) LPLs levels in ventricular myocardia in right coronary artery occlusion-induced myocardial ischemia for 3 min without arrhythmias (n = 5 in each group). Isch ischemia, VT ventricular tachycardia, AVB: III° atrioventricular block, VF ventricular fibrillation, Rec 1 the ECG recovered to normal following transient I°–II° atrioventricular block, Rec 2 the ECG recovered to normal following transient III° atrioventricular block.
