Effect of low-frequency low-intensity ultrasound on contractile function of isolated heart

Stimulation of the isolated heart with low-intensity low-frequency ultrasound produced a positive inotropic effect (at certain ultrasound intensity). This effect manifested in increased systolic and pulse intraventricular pressures and persisted for tens of minutes after the end of sonication.
