超声波的一种新用途正在研究中:刺激心肌收缩。加拿大国家研究委员会(NRC)和渥太华大学心脏科的研究人员称,迄今为止,根据人的动脉组织、离体的动物心脏和开胸的动物研究发现,超声波可使收缩压增加一倍,而舒张压却下降。研究人员预料超声波可在一年内用于人心脏,可能使心脏外科病人免作心脏手术,也可将超声波装在除颤器的电极板上,或装在导管的顶端,构成一个点状刺激。研究组的成员 A new use of ultrasound is under study: to stimulate myocardial contractions. Researchers from the Canadian National Research Council (NRC) and the University of Ottawa Cardiology have so far found that studies of human arterial tissue, isolated animal hearts and thoracic animals have found that ultrasound can double systolic blood pressure and diastolic Pressure drop down. Researchers expect the ultrasound to be applied to the human heart within a year, to free heart surgery patients from heart surgery, to place the ultrasound on the defibrillator’s electrode plate or tip of the catheter to create a punctate stimulus.
