新华网1月22日电 内科医生能够通过听诊器和耳朵判断病人的心脏状况已非新鲜事。然而，仅凭听诊器，像心脏杂音这样的细微问题会不会被忽略掉？据美国科技博客Gizmodo报道，HD Medical公司推出了一款数码听诊器，能够有效帮助医生发现心脏问题。
这款名为ViScope MD的数码听诊器在普通听诊器的基础上加入了音频滤波器、读数器以及心脏杂音自动探测功能。通过使用数码听诊器，医生听到的内容变得更加清晰，从而保证不漏过任何一个细节。
据报道，ViScope MD的售价为600美元（约合人民币3600人民币），价格比普通的听诊器高出许多。然而，ViScope MD配备的心音图显示器，能够在心脏有杂音的情况下准确地监测心率。此外，通过ViScope MD传到医生耳朵里的声音也经过了数字化处理。如此一来，医生不仅可以调整音量大小，还能将一部分声音过滤掉，从而监控心脏不同部分的状况。除上述功能外，ViScope MD的显示器能在测量到心脏杂音后显示警告，还能记录下10秒心脏波形，并取正常的心率进行对比。
这样一款数码听诊器是否能确保任何心脏问题都医生掌控之下呢？或许不能，但它的确可以让漏诊的几率降低不少。

Physicians have been successfully diagnosing heart conditions using just their stethoscopes and ears for years now. But how many particularly subtle issues, like heart murmurs, have gone unnoticed?
With the ViScope MD from HD Medical Inc., hopefully none ever do. It adds audio filters, a visual readout, and automatic murmur detection to a standard stethoscope to enhance what doctors already hear, ensuring nothing gets missed.
At $600 the ViScope MD is certainly far more expensive than your run-of-the-mill stethoscope, but the inclusion of a phonocardiogram display means that heart rates can be accurately monitored visually in noisy situations. The sound delivered to the ears is actually digital, too, so not only can it be turned up, it can also be filtered to let the user distinguish and tune in to different parts of the heart.
The most interesting feature, though, is the ViScope MD's ability to listen for heart murmurs, and then display obvious warnings when one has been detected. It can even record ten-second waveform samples to be later analyzed further or compared against a normal heart rate.
Will it absolutely guarantee nothing gets missed? Probably not. But serving as a second set of digital ears certainly helps reduce the chances of a serious medical issue going undetected.
