Abstract
Acoustic cavitation induced by continuous focused ultrasound (1.4 W/cm2, 543 Hz) was found to result in reversible membrane depolarization (by 54 mV), loss of excitability and contracture in the rat papillary muscles. The same intensities of impulse ultrasound had positive inotropic effects.
摘要
连续聚焦超声（1.4瓦/平方厘米，543赫兹）诱导的声空化被发现会导致大鼠乳头肌出现可逆性膜去极化（54毫伏）、兴奋性丧失和挛缩。相同强度的脉冲超声具有正性肌力作用。
