持续的或慢性的心律失常,可能会减少心搏出量,降低血压,影响重要器官的血液灌注,并会加速心力衰竭。
Ongoing arrhythmia in some heart diseases can reduce the heart's ability to supply the body with blood and can lead to heart failure.
心输出量增加,心脏收缩加强能泵更多的血液,心搏量增加,左心室壁变厚(更多肌肉),心脏对氧气的需要减少。
Increases Cardiac Output, stronger heart contractions pump more blood, increased stroke volume, thickens left ventricle wall (more muscular), decreases hearts' oxygen requirements.
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.
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.
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.
