一種新型系統(tǒng)可以進(jìn)行應(yīng)激心電圖(ECG)，還可以進(jìn)行高頻率中位QRS分析，為檢查缺血性心臟疾病提供了有效的非創(chuàng)傷性方法。

在2005年9月瑞典斯德哥爾摩舉行的歐洲心血管學(xué)會(huì)年會(huì)上，報(bào)道了對(duì)HyperQ應(yīng)激系統(tǒng)的大規(guī)模臨床研究的結(jié)果。這項(xiàng)研究涉及了900例患者，接受了過單光子發(fā)射計(jì)算機(jī)掃描的心肌灌注成像檢查(SPECT)。研究結(jié)果提示，HyperQ檢查顯著改進(jìn)了對(duì)應(yīng)激檢查的能力，敏感性為78%，特異性為86%。

HyperQ應(yīng)激系統(tǒng)使用復(fù)雜的ECG信號(hào)分析，對(duì)心臟缺血進(jìn)行可靠的檢查，主要依據(jù)的是ECG高頻成分。該系統(tǒng)已經(jīng)獲得了美國食品藥品管理局的許可，并得到了CE標(biāo)記。

“由BSP開發(fā)的抽取HyperQ信號(hào)的該項(xiàng)技術(shù)，能夠整合用于各種臨床檢查系統(tǒng)，為缺血性疾病提供無與倫比的檢測能力。” 生物信號(hào)處理有限公司(BSP, Tel Aviv, Israel)創(chuàng)始人兼首席執(zhí)行官Amir Beker博士如此說到，正是該公司開發(fā)了HyperQ系統(tǒng)。該公司建立于2000年，主要由信號(hào)處理專家、生物醫(yī)學(xué)工程師、和臨床醫(yī)生組成。該公司獲得的大量資金資助來自以色列工業(yè)和商業(yè)部首席科學(xué)家事務(wù)處(OCS)，用以支持BSP公司的下一個(gè)產(chǎn)品HyperQ靜息監(jiān)視器。

System to Detect Cardiac Ischemia
 
A new system for performing a stress electrocardiogram (ECG) also allows high-frequency mid-QRS analysis, offering an effective noninvasive tool for the detection of ischemic heart disease.

Results from a large-scale study of the HyperQ stress system were presented at the annual meeting of the European Society of Cardiology Congress in Stockholm (Sweden) in September 2005. The study involved 900 patients referred for myocardial perfusion imaging by single photon emission computed tomography (SPECT). The results indicated that the HyperQ analysis significantly improved the diagnostic ability of the stress test, reaching a sensitivity of 78% and specificity of 86%.

The HyperQ stress system uses sophisticated analysis of the ECG signal to provide a reliable measure for cardiac ischemia, based on the high-frequency components of the ECG. The system has been cleared by the U.S. Food and Drug Administration (FDA) and has received the CE Mark.

“The technology developed by BSP to extract the HyperQ signal can be ntegrated within a wide range of clinical systems, offering unmatched detection abilities for ischemic conditions,” said Dr. Amir Beker, founder and CEO of Biological Signal Processing Ltd. (BSP, Tel Aviv, Israel), which developed the HyperQ system. The company was founded in 2000 by signal-processing experts, biomedical engineers, and clinicians. The company has been awarded a large grant by the Office of the Chief Scientist (OCS) of the Ministry of Industry and Trade in Israel for the development of BSP’s next product, the HyperQ Rest Monitor.
