数字听诊器如何工作？

数字听诊器已放置在袖带外，当 BPM Core 放在左上臂时，听诊器便可与左胸接触。该设备将听取心音 20 秒，并检测是否存在心脏瓣膜病的风险。

这种测量获得医学认可了吗？

This recording is a big innovation and has received CE clearance for medical devices. BPM Core is currently under review to be FDA cleared.

我可以从测量中了解到什么，又该如何据此采取行动呢？

BPM Core 让用户知道自己是否存在心脏瓣膜病的风险，并鼓励用户看心脏科医生。疾病诊断越早，心脏科医生就可以更好地跟踪病情演变并最终在需要时计划手术。

Note: You will initially need 5 successful measurements before receiving the results of your stethoscope recordings. If you didn’t take ECG and heart sounds recordings during the last 6 months, you will have to follow this process again.

Results you may see

Several measurements are needed in order to give a precise analysis of your heart sounds. You can see the number of measurements you’ve taken in the Withings Health Mate app.

• Normal heart sounds: Your heart doesn't show evidence of valvular heart disease.
• Signs of valvular heart disease: Your heart sounds may show signs of valvular heart diseases.
• Inconclusive: An inconclusive result means the recording can't be classified. This can happen for many reasons such as too much noise in the signal, or due to a wrong position of the stethoscope.

Please note that an ECG is needed for the heart sounds analysis. This is why an inconclusive ECG will lead to an inconclusive heart sounds report.

Please, consult your doctor if your heart sounds show evidence of valvular heart diseases or if you feel shortness of breath, heart pains or palpitations.
