休斯敦消息:研究人员指出,已设计的一种测定心脏的呼吸性窦性心律不齐(RSA)的仪器可以提供一种非损伤、无痛及迅速调节阿霉素心毒性的方法。该仪器的发明人William J Hrushesky说,这种仪器间接地测定心脏的硬度,反映心脏整个结构的健康状态。他说在此地召开的美国临床肿瘤学家学会的会议上报告了该仪器临床首次应用中,研究人员评价了阿霉素对20例癌症病人心脏的影响。明尼苏达大学内科副教授Hrushesky说,RSA在平静状态下吸气和呼气时的心率差在年轻的运动员可以高达每分钟20次,在年长病人或心脏病病人可以低至零次。但迄今为止,由于 HOUSTON: The researchers pointed out that a device designed to measure respiratory sinus arrhythmias (RSA) in the heart can provide a non-invasive, painless and rapidly regimen of adriamycin cardiotoxicity. William J Hrushesky, inventor of the device, said the instrument measures the hardness of the heart indirectly, reflecting the health of the entire structure of the heart. He said at a meeting of the American Society of Clinical Oncologists here that the first clinical application of the device was reported, the researchers evaluated the effects of doxorubicin on the heart of 20 cancer patients. Hrushesky, MD, associate professor of internal medicine at the University of Minnesota, said RSA’s heart rate difference between inspiration and expiration during calm can be as high as 20 beats per minute for young athletes and as low as zero for an elderly patient or a heart attack. But so far, thanks
