    • The present invention relates to a system and a process for detecting, assessing, grading and diagnosing heart conditions in human beings. The system includes a device for providing or generating an acoustic blood flow signal and a signal representative of the electrical activity of a subject's heart. The device for providing the acoustic blood flow (MCG) signal may be a transducer or microphone attached to the patient, or in the alternative, an acoustic signal stored in a storage device. The device for providing the electrical activity (ECG) signal may be an electrocardiogram device attached to the subject or a stored ECG signal. The ECG signal is conditioned in a conditioning circuit to provide a timing or calibration signal having QRS spikes at the onset of each systolic portion of a heart cycle. The MCG signal passes through its own conditioning circuit to filter out unwanted noise and to amplify low frequency sounds. The timing signal and the MCG signal are fed into a microprocessor wherein the MCG signal is converted in a spectral pattern of heart sounds and matched with the timing signal. The output from the microprocessor is a combined, real time MCG pattern/ECG wave signal which may be displayed on a video monitor, which may be put into hard copy form, and/or which may be stored on a storage device.
    • 本发明涉及一种用于检测,评估,分级和诊断人类心脏病状的系统和方法。 该系统包括用于提供或产生声学血流信号和表示受试者心脏的电活动的信号的装置。 用于提供声学血流(MCG)信号的装置可以是附接到患者的换能器或麦克风,或者替代地,存储在存储装置中的声信号。 用于提供电活动(ECG)信号的装置可以是附接到对象的心电图装置或存储的ECG信号。 在调节电路中调节ECG信号,以在心脏周期的每个收缩期部分开始时提供具有QRS尖峰的定时或校准信号。 MCG信号通过其自己的调理电路来滤除不需要的噪声并放大低频声音。 定时信号和MCG信号被馈送到微处理器中,其中MCG信号以心音的频谱图形转换并与定时信号匹配。 来自微处理器的输出是组合的实时MCG模式/ ECG波信号,其可以显示在视频监视器上,该视频监视器可以被放置在硬拷贝形式中,和/或可存储在存储设备中。
