Digital stethoscope

The embodiment of the utility model discloses a digital stethoscope, which is characterized in that a common stethoscope head, a control part and an electrocardio and heart sound stethoscope head are arranged in the digital stethoscope, an electrode slice arranged on the electrocardio and heart sound stethoscope head obtains electrocardio wave information with the maximum amplitude, and accurate electrocardio wave data are obtained through a signal processing module. A heart sound sensor in the electrocardio heart sound auscultation head collects heart sound wave information, and accurate heart sound wave data are obtained through a signal processing module. Furthermore, a wireless communication module in the control part transmits the received electrocardiographic wave data and cardiac sound wave data to external display equipment which is in wireless communication connection with the wireless communication module, so that the effect of displaying electrocardiographic and phonocardiogram in real time is real
