以每搏心输出量减少、左室射血时间缩短为其损伤特点。
The time of ejecting blood was shortened significantly in the left ventricle.
结论：磁场可降低蟾蜍心肌收缩性能而导致每搏心输出量减少，对舒张功能影响不明显。
Conclusion: magnetic field may decrease the myocardial contractility of isolated toad heart and no obvious effect to the function of the myocardial relax.
结果表明，用线性回归模型计算的左室射血分数、每搏量、心输出量在较低心率时模拟数值较为可信，在较高心率时每搏量模拟数值不可靠。
It showed that the simulation results of LVEF, SV and CO were reliable at a low heart rate with linear regression model, but unreliable at a high heart rate.
心排血指数（CI）及每搏输出量（SV）升高或下降不一致，但均接近正常范围。
The levels of CO, CI and SV increase or decrease were different, but all approached to normal range.
